Metz et al\, Phys. Rev. Let t. 83\, 1542 (1999)). This event was the culmination of a series of experi mental findings that have revealed the presence of symmetry and order in a tomic nuclei (a complex system composed of hundreds of particles interacti ng strongly). In this talk\, first the concept of dynamic symmetry will be introduced and applied to the study of nuclear spectra. Then\, the even m ore unifying concept of dynamic supersymmetry (F. Iachello\, Phys. Rev. Le tt. 44\, 772 (1980)) will be defined and the series of events that led to the present discovery presented. Implications of the discovery of supersym metry in nuclei to other fields of physics\, such as particle physics wher e supersymmetry has been sought for years\, but not yet found\, and to oth er complex systems (macromolecules\, polymers\, ·)\, where supersymmetrie s of the type found in nuclei could occur\, will be briefly discussed.Orga niser(s): Serge Franchoo / EP DivisionNote: For more information\, please contact the scientific secretary of the workshop Serge Franchoo (serge.fra nchoo@cern.ch) or the ISOLDE secretary (isolde.secretariat@cern.ch)\n\nhtt p://indico.cern.ch/conferenceDisplay.py?confId=a033399 LOCATION:CERN Council Chamber URL:http://indico.cern.ch/conferenceDisplay.py?confId=a033399 END:VEVENT BEGIN:VEVENT SUMMARY:ISOLDE Physics Workshop and Users Meeting DTSTART;VALUE=DATE-TIME:20010921T063000Z DTEND;VALUE=DATE-TIME:20010921T143000Z DTSTAMP;VALUE=DATE-TIME:20130518T192229Z UID:indico-event-a033408@cern.ch DESCRIPTION:The ISOLDE Collaboration and the ISOLDE Physics Group jointly organize a Physics Workshop and Users Meeting.

Two ex perimental methods were applied: analysis of the antiproton annihilation r esidues one mass unit lighter than the target mass by nuclear spectroscopy and the measurement of strong interaction effects on antiprotonic level w idths and shifts. Assuming densities in the form of a two-parameter Fermi distribution neutron densities and differences of root mean square radii o f neutron and proton distributions were determined for 26 isotopes (for a wide mass range: 4060)\, which occurs during the various phases of stellar evolution m ostly through slow and rapid neutron capture processes. While the main fea tures of stellar nucleosynthesis are now well understood\, a more refined modelling of the elemental abundances\, and of the chemical evolution of t he Universe\, requires accurate new data on various isotopes\, either rare \, radioactive\, or with low cross-sections\, on which scarce and discrepa nt data exist to date.\nNew and accurate neutron data are also required in the field of Nuclear Technology\, for improving the safety and efficiency of current nuclear reactors and\, especially\, for the development of adv anced systems\, such as sub-critical Accelerator Driven Systems and Genera tion IV fast reactors\, that would overcome major drawbacks of present tec hnology\, in particular the inefficient use of uranium resources and the p roduction of long-lived nuclear waste. The design and operation of these n ew systems require high-precision cross-section data on a long list of iso topes\, mostly radioactive\, in particular plutonium\, minor actinides\, f ission fragments and structural materials.\nBased on an idea of Rubbia\, t he spallation neutron source n_TOF was built ten years ago at CERN\, to ad dress some of the pressing needs of accurate new data on neutron cross-sec tions. The facility\, based on the spallation of 20 GeV/c protons on a wat er-cooled Pb targer\, is characterized by the combination of high neutron flux\, excellent energy resolution\, low backgrounds and very low duty cyc le\, resulting in the most luminous neutron source world-wide. All these f eatures make n_TOF a unique installation\, in particular for the measureme nt of radioactive isotopes. The excellent performance of the facility is c omplemented by the use of the most advanced detection and data acquisition techniques\, providing the ideal environment for neutron time-of-flight e xperiments covering the full energy range of astrophysical and nuclear tec hnology interest.\nAfter a brief description of the n_TOF facility and of the experimental setups used for capture and fission measurements\, a revi ew of the results obtained in the first measurement campaign at CERN will be presented in this seminar. The features of the n_TOF facility have rece ntly been further improved by refurbishing the spallation target\, and by modifying the experimental area to allow handling of radioactive samples. Following these changes\, a new\, rich experimental campaign has just star ted. An overview of the future measurements proposed by the n_TOF Collabor ation for the next few years will be presented.\n\nhttp://indico.cern.ch/c onferenceDisplay.py?confId=101450 LOCATION:CERN 26-1-22 URL:http://indico.cern.ch/conferenceDisplay.py?confId=101450 END:VEVENT BEGIN:VEVENT SUMMARY:Carreer opportunities for young engineers and applied physicists w ithin CATHY-ITN DTSTART;VALUE=DATE-TIME:20100804T123000Z DTEND;VALUE=DATE-TIME:20100804T131500Z DTSTAMP;VALUE=DATE-TIME:20130518T192229Z UID:indico-event-103245@cern.ch DESCRIPTION:CATHI is a mono-site Initial Training Network (ITN)\, with CER N as main host institution\, offering research training in the application of advanced accelerator technology\, beam instrumentation\, ultra-high va cuum\, cryogenics\, radiation protection and advanced material technologie s in one of Europe’s leading Radioactive Ion Beam facilities (ISOLDE) at CERN\, and its future upgrade (HIE-ISOLDE).

A method used to measure the mass of short-lived nuclei\, applied to the 11Li case will be discussed. The experimental angular distribution of the two halo-neutron transfer reaction 1H(11Li\,9Li)t at 4.3A MeV\, using the MAYA detector as a thin target\, will be presented and compared to coupled reaction channel calculations including 3-body models in order to extract informations on the structure of the 11Li halo. The extraction of the 11Li+p optical poten tial using the data on the elastic scattering\, will also be discussed. Fi nally\, the excitation function of the resonant elastic scattering reactio n\, determined using the MAYA detector as a thick target\, will be present ed.

ADS systems require a hi gh-intensity (several mA) proton beam that runs under very stable conditio ns. Recently\, the pre-design phase has been completed.\n\n Using part of the proton-beam intensity (100-200 uA) from the MYRRHA accelerator in para sitic mode and sending it to a ruggedized target-ion source system of an I SOL facility allows production of high-intensity RIBs for extended periods of time (up to several months). This system\, called ISOL@MYRRHA\, opens perspectives for unique RIB research complementing the activities at other facilities.\n\n After discussing the technical considerations of ISOL@MYR RHA\, an overview will be presented of the unique physics opportunities in various research fields (fundamental interactions\, condensed matter\, nu clear structure\, atomic physics\, and medical applications)\, which will become possible.\n\nhttp://indico.cern.ch/conferenceDisplay.py?confId=1104 21 LOCATION:CERN 26/1-022 URL:http://indico.cern.ch/conferenceDisplay.py?confId=110421 END:VEVENT BEGIN:VEVENT SUMMARY:Onsets of nuclear deformation from measurements with the Isoltrap mass spectrometer DTSTART;VALUE=DATE-TIME:20101117T133000Z DTEND;VALUE=DATE-TIME:20101117T141000Z DTSTAMP;VALUE=DATE-TIME:20130518T192229Z UID:indico-event-110788@cern.ch DESCRIPTION:Mass measurements provide important information concerning nuc lear structure. This work presents results from the pioneering Penning tra p spectrometer ISOLTRAP at CERN-ISOLDE. High-precision mass measurements o f neutron-rich manganese (58−66Mn) and krypton isotopes (96\,97Kr) are p resented\, of which the 66Mn and 96\,97Kr masses are measured for the firs t time. In particular\, the mass of 97Kr was measured using the preparatio n trap and required the definition of a new fit function.\nIn the case of the manganese isotopes\, the N = 40 shell closure is addressed. The two-ne utron-separation energies calculated from the new masses show no shell clo sure at N = 40 but give an estimation of the proton-neutron interaction (a round 0.5 MeV) responsible for the increase of collectivity and nuclear de formation in this mass region. The new krypton masses show behavior in sha rp contrast with heavier neighbors where sudden and intense deformation is present\, interpreted as the establishment of a nuclear quantum shape/pha se transition critical-point boundary.

For example\, the changes in the large gaps observed in data for two-nucleon separation energies are often interpreted as due to the evolution of shell structure with N and Z . In Bender et al\, Phys. Rev. C78 (2008) 054312\, we showed that data can be explained in a coherent manner within mean-field-based models using an energy density functional (EDF) as due to a combination of the slow varia tion of spherical single-particle spectra and the rapid variation of colle ctive correlation effects. The latter corresponds to fluctuations in shape degrees of freedom and require the restoration of symmetries broken by th e self-consistent mean field and the mixing of configurations with differe nt intrinsic deformation in the framework of the generator coordinate meth od.\nI will present the extension of this analysis to a mass filter called delta Vpn that is often identified with the proton-neutron interaction in nuclei.\n\nhttp://indico.cern.ch/conferenceDisplay.py?confId=120713 LOCATION:CERN 26-1-022 URL:http://indico.cern.ch/conferenceDisplay.py?confId=120713 END:VEVENT BEGIN:VEVENT SUMMARY:Early onset of deformation in the neutron-deficient polonium isoto pes identified by in-source resonant ionization laser spectroscopy DTSTART;VALUE=DATE-TIME:20110216T133000Z DTEND;VALUE=DATE-TIME:20110216T141000Z DTSTAMP;VALUE=DATE-TIME:20130518T192229Z UID:indico-event-127287@cern.ch DESCRIPTION:The technique of resonant ionization spectroscopy is well know n for its selectivity in the production of RIB at ISOL facilities. This fe ature is now also used for atomic spectroscopy on weakly-produced isotopes (<1 atom/s)\, otherwise not accessible by conventional laser spectroscopy techniques.\nWith two protons outside the lead (Z=82) closed core\, the p olonium isotopes (Z=84) exhibit shape coexistence on the neutron-deficient side of the nuclear chart. The influence of intruding deformed configurat ions on the ground state and long-lived isomers from 191Po up to the N=126 (210Po) shell closure and beyond has thus been investigated by means of i n-source resonant ionization laser spectroscopy over two campaigns at CERN ISOLDE using the laser ion source. The isotope shifts between all the iso topes have been extracted and large-scale atomic calculations have been us ed to determine the electronic parameters necessary to deduce changes in t he mean-square charge radii (mscr). The extracted changes in the mscr devi ate much earlier than predicted by nuclear models and point towards a well -deformed ground state from 198Po downwards\, much earlier than suggested by alpha-decay and in-beam studies of those isotopes.\nAfter briefly intro ducing the technique and the challenges posed by the atomic calculations\, we report in this contribution on the nuclear structure observables extra cted (charge radii and electromagnetic moments) and their impact on our un derstanding of the shape coexistence phenomenon in this region of the nucl ear chart.\n\nhttp://indico.cern.ch/conferenceDisplay.py?confId=127287 LOCATION:CERN 26-1-022 URL:http://indico.cern.ch/conferenceDisplay.py?confId=127287 END:VEVENT BEGIN:VEVENT SUMMARY:Nuclear power and Safety DTSTART;VALUE=DATE-TIME:20110316T133000Z DTEND;VALUE=DATE-TIME:20110316T141000Z DTSTAMP;VALUE=DATE-TIME:20130518T192229Z UID:indico-event-131530@cern.ch DESCRIPTION:In the light of the recent incidents at the Fukushima power pl ant in Japan\, a factual take on safety in nuclear power plants will be pr esented.\n\nhttp://indico.cern.ch/conferenceDisplay.py?confId=131530 LOCATION:CERN 26-1-022 URL:http://indico.cern.ch/conferenceDisplay.py?confId=131530 END:VEVENT BEGIN:VEVENT SUMMARY:Nuclear excitons and control of gamma-ray emission DTSTART;VALUE=DATE-TIME:20110323T133000Z DTEND;VALUE=DATE-TIME:20110323T141000Z DTSTAMP;VALUE=DATE-TIME:20130518T192229Z UID:indico-event-126773@cern.ch DESCRIPTION:Resonant scattering of light off nuclei in a crystal may lead under certain conditions to the formation of a nuclear exciton.

Its explanation by Gamow in 1928 required the acceptance of the probabilistic interpretation of quantum mechanics. The Gamow theory is so simple and successful that even today it is intensively applied in radioactive decay studies. One can assert that this is an effe ctive theory\, where the formation process of alpha particle in atomic nuc leus is totally neglected. A proper microscopic description of the alpha f ormation is a challenging undertaking and was made possible rather recentl y by applying the nuclear shell model. In this talk I will give a brief re view on the recent progresses made in the microscopic study of the alpha f ormation process. One thus obtains a generalization of the Geiger-Nuttall law that holds for all alpha and heavier cluster radioactivities. This may help us in understanding the influence of nuclear structure on the decay properties. In particular\, it allows one to use alpha decay as a tool to investigate the shell structure and pairing properties of very neutron-def icient isotopes around Z=82 produced at the CERN ISOLDE facility.\n\nhttp: //indico.cern.ch/conferenceDisplay.py?confId=145570 LOCATION:CERN 26-1-022 URL:http://indico.cern.ch/conferenceDisplay.py?confId=145570 END:VEVENT BEGIN:VEVENT SUMMARY:Experimental evidences for low-lying octupole isovector excitation s DTSTART;VALUE=DATE-TIME:20110727T123000Z DTEND;VALUE=DATE-TIME:20110727T131000Z DTSTAMP;VALUE=DATE-TIME:20130518T192229Z UID:indico-event-145571@cern.ch DESCRIPTION:\n An evaluation of data obtained in (n\, n'gamma) experiment s revealed strong 3−i -> 3−1 M1 transitions in nuclei near the N=50 ( 94Mo and 96Mo)\, Z=50 (112Cd and 114Cd) and N=82 (144Nd) shell closures.  The observed <3−1 ||M1||3−i> matrix elements scale with the <2+1 ||M1| |2+ms> matrix elements.

Further evidence for a possible one-phonon nature of the octupole states of interest is provi ded by the (e\, e') and (p\, p') reactions.

In both cases\, the r esonant ionization laser technique provides an elegant and effective way t o improve purity of the radioactive beams but also to access the propertie s of isomeric states.\nIn the seminar the recent results obtained from the analysis of Coulomb excitation of isomeric states of 70Cu will be present ed\, as well as the study of properties of shape-coexisting states in neut ron deficient mercury isotopes probed through the beta-decay of laser ioni zed thallium isotopes.\n\nhttp://indico.cern.ch/conferenceDisplay.py?confI d=155734 LOCATION:CERN 26-1-022 URL:http://indico.cern.ch/conferenceDisplay.py?confId=155734 END:VEVENT BEGIN:VEVENT SUMMARY:Extraction of absolute spectroscopic factors from knockout and tra nsfer reactions on light exotic nuclei DTSTART;VALUE=DATE-TIME:20111006T090000Z DTEND;VALUE=DATE-TIME:20111006T094000Z DTSTAMP;VALUE=DATE-TIME:20130518T192229Z UID:indico-event-157109@cern.ch DESCRIPTION:\n The distribution of spectroscopic strength in nuclei can be extracted from direct-reaction cross section measurements\, as one-nucle on knockout at intermediate energy or transfer at low energy. The study o f deeply-bound nucleon removal from several sd-shell nuclei having a large difference of proton-neutron separation energies\, DeltaS=Sp-Sn~20 MeV\, exhibits experimental cross sections about four times smaller than theor etical predictions from state-of-the-art calculations. This trend is not observed from (d\,p) transfer reactions with nuclei having smaller separat ion energy asymmetry\, DeltaS=12 MeV.\n\n To investigate the origin of th is reduction\, we have performed two complementary experiments for the 14 O case having a large energy asymmetry: (i) one-nucleon knockout from 14O (53 MeV/n) and 16C (75 MeV/n) on a 9Be target at the NSCL\; (ii) one-nucl eon transfer reaction using SPIRAL beam\, 14O(d\,t)13O and 14O(d\,3He)13N at 18 MeV/n\, and the MUST2 array.

DNA molecules provide ba sic building blocks for constructing functionalized nanostructures with tw o major features: self-assembly and programmability. In this talk\, we pre sent on self-assembled various DNA nanostructures and their applications. 1D and 2D periodically patterned nanostructures utilizing several distinct DNA motifs such as cross tiles\, double crossover tiles as well as single -stranded tiles will be discussed with unique design schemes and character istics. We have demonstrated fabrication of size-controllable\, fully addr essable\, and precisely programmable DNA-based nanostructures. Especially in construction of “working” devices\, properly designed DNA lattices can serve as a controllable and programmable scaffold for organizing nanom aterials such as protein or nanoparticles. DNA-templated metallic nanowire s using a chemical deposition method might be a good example. We discuss e lectrical measurement through silver nanowires and propose possibilities o f the construction of physical devices and biological/chemical sensors bas ed on DNA lattice. We also briefly discuss feasibility of radioactive ion beam based study of artificial DNA molecules. Radioactive ion beam have be en used for studying condensed matters and are about to investigate biomat erials as well for its probing the conformation and dynamics of biomolecul es in aqueous solution. These innovative and authentic characterization te chniques may lead to the fabrication of new and complex biological structu res with high production yield and functional performance efficiency in de vices and sensors’ application in near future.\n\nhttp://indico.cern.ch/ conferenceDisplay.py?confId=157392 LOCATION:CERN 26-1-022 URL:http://indico.cern.ch/conferenceDisplay.py?confId=157392 END:VEVENT BEGIN:VEVENT SUMMARY:TRLO II - flexible FPGA trigger control DTSTART;VALUE=DATE-TIME:20111024T120000Z DTEND;VALUE=DATE-TIME:20111024T124000Z DTSTAMP;VALUE=DATE-TIME:20130518T192229Z UID:indico-event-158839@cern.ch DESCRIPTION:The GSI-developed FPGA logic module VULOM can be used with the TRLO II firmware.  It then provides an enhanced digital trigger and expe riment control\, with coincidence building\, dead-time locking\, and downs cale.

This was stimu lated by the high-resolution experimental finding that the ratio of the hy perfine structure interaction constants\, a\, differed from the ratio of i ndependently measured nuclear gyromagnetic ratios\, g\, by more than 1/3 p ercent for the two stable isotopes of rubidium\, 85Rb and 87Rb. This was a set of isotopes particularly prone to this effect as they differed in nu clear spin\, respectively 5/2 and 3/2. The theory had to account not only for this relatively fine effect\, but also\, of course\, for the individu al nuclear magnetic moments. The latter was done at the time by using eff ective gs or gl values to explain departures of measured nuclear magnetic dipole moments from the Schmidt limits. A significant advance in theoreti cal work for the moments of odd-A nuclei was made by Arima\, Horie and co- workers [2] by considering first order nuclear configuration mixing in the nucleon-nuclear interaction. Their results brought experiment and theory into reasonable agreement over the entire landscape of nuclei. This basi s was used subsequently to account for the influence of the distributed nu clear magnetization on the magnetic dipole (M1) hyperfine structure intera ction [3]\, i.e. the Bohr-Weisskopf (BW) effect. The calculations involve appropriate M1 matrix elements and the solution of the Dirac equation in the field of a distributed nuclear charge corresponding to one given by hi gh-energy elastic electron scattering. They also require the evaluation of nucleon radial parameters in the nuclear field\, the latter being taken as represented by a Saxon-Woods potential. Parameters required for the e valuation of the BW effect were average values\, but useful for overall ca lculations for all the isotopes that were measured\, as well as those anti cipated to be measured at the time. Considerable progress in the measurem ents has been made in the intervening years\, particularly with the use o f laser spectroscopy\, and at radioactive beam facilities\, such as ISOLDE [4]. The BW effect calculations will be extended to these nuclear region s.\n\nWhile many more sophisticated nuclear calculations are possible in p articular cases\, it is useful to extend the BW effect overall studies. The nuclear parameters used are possibly too simplistic\, but in view of t he extensive experimental work that has been done from low to high Z\, th ey are expected to serve the interpretation of new measurements. For examp le\, in uranium and beyond\, the BW effect could be in the few percent ran ge. (In muonic atoms in this region\, BW is a fifty percent effect.) Fo r halo nuclei\, BW may add useful pertinent insight [5]. The starting poi nt in this work is the nuclear spin assignment. If one considers the usua l shell-model orbits\, the measured odd nucleon angular momenta can fit in to assignment between the magic numbers. Beyond N=126\, the listed spins shortly appear to loose their regularity\, though one could still account for them in terms of the possible lowest shell model levels. But\, we had a lesson many years ago from Maurice Goldhaber (who by the way measured t he helicity of the neutrino)\, who questioned the spin value of 203Hg infe rred from the beta decay and stimulated a direct optical spectroscopic mea surement [6]: this showed the decay analysis to give an erroneous value. Spins listed in nuclear tables\, if not obtained by optical spectroscopic or NMR techniques\, may not be the unquestionable truth! Our calculation s therefore will have to allow for a number of possible spin/parity assign ments. This talk reviews the physics underlying both the BW (magnetizatio n distribution) and Breit-Rosenthal (charge distribution) effects on the h yperfine structure interaction and describe the calculations and nuclear p arameters used in the extension of their study to the new body of experime ntal data. Particle-core coupling is not considered in this work\, but on e may have to account for it in individual cases.\n\n[1] Aage Bohr and V.F . Weisskopf\, Phys. Rev. 77\, 94 (1950).\n[2] A. Arima and H.

Being in routine ope ration for investigations of surface effects in super- and semiconducting materials\, the zero-field beta-NQR technique provides a powerful tool f or extracting ratios of quadrupole moments of radioactive nuclei. Recently \, this technique was applied for the first time with a nuclear physics g oal to investigate the quadrupole moments of the neutron-rich lithium iso topes.\n\n The addition of a radio-frequency quadrupole cooler and buncher (RFQ) in front of the polariser beamline allows collinear laser spectros copy to be performed with increased sensitivity. This permits measurement s to be made on exotic species where ion beam production efficiencies are low. This technique is well established and capable of determining the m ost fundamental nuclear ground state properties\, such as its spin\, elec tromagnetic moments and mean-square charge radius\, in a nuclear model in dependent way. Laser spectroscopy has been carried out with a view to asce rtain the mean-square charge radius of the dripline N=Z nucleus Rb-74.\n\ n At present\, a particular interest lies in the neutron deficient franciu m isotopes to carry forward the program started at Stony Brook University in determining the nuclear magnetisation distribution.

Its main characteristics will be the installation of a pneu matic transport system capable of activating appropriate materials with th e proton beam downstream\, behind the ISOLDE production targets\, before t he beam is lost in the beam dumps. Indeed CERN high energy protons loose o nly 10% of their energy past the ISOLDE production targets\, and are thus still capable of producing isotopes in an additional target irradiation st and for the present purposes. The clear advantage is that this program can be carried out without the need to fit in the streamline of the ISOLDE ap proved and scheduled experimental program. The infrastructure\, for its op timal performance\, needs in addition a radiochemical laboratory equipped with appropriate hot-cells and an isotope mass spectrometer\; this type of infrastructures has shown to provide batches of carrier-free medical isot opes.

Isotopes wit h one or a few additional neutrons are not only heavier than others but\, more often than not\, also exhibit quite different charge and magnetizat ion distributions. Using laser spectroscopy\, precise isotope shift measu rements have been carried during the last decade along different isotopic chains and were found a versatile alternative to x-ray measurements in m uonic atoms or electron scattering.\nHowever\, in order to extract useful information about the nuclear structure and radii from shifts in the ato mic transition frequencies\, the `electronic response' to the nuclear cha nges need to be known in sufficient detail. Apart from King-plot techniqu es\, which applies information from different stable isotopes\, atomic st ructure theory may help understand and provide this response in terms of mass- and field-shift parameters for optical transitions of interest. Up to the present\, however\, little is known about these isotope parameters for most transitions in medium and heavy elements and\, especially\, for ions with complex shell structures. Difficulties in applying atomic theo ry arise\, in particular\, from the relativistic motion and the number of electrons in such atoms and ions as well as from (nearly) degenerate con figurations. --- In this seminar\, I shall outline these difficulties and discuss the recent successes (and failures) in calculating accurate isot ope-shift parameters. Examples from medium-to-large scale atomic computat ions are presented and display how sensitive the isotope parameters behav e with regard to the electronic shell structure and correlations. A few c onclusions are drawn about which optical transitions might be less sensit ive to correlation effects and\, hence\, useful for laser-spectroscopic s tudies.\n\nhttp://indico.cern.ch/conferenceDisplay.py?confId=181836 LOCATION:CERN 26-1-022 URL:http://indico.cern.ch/conferenceDisplay.py?confId=181836 END:VEVENT BEGIN:VEVENT SUMMARY:Lecture series on heavy and super heavy elements (1/3) DTSTART;VALUE=DATE-TIME:20120509T123000Z DTEND;VALUE=DATE-TIME:20120509T133000Z DTSTAMP;VALUE=DATE-TIME:20130518T192229Z UID:indico-event-186627@cern.ch DESCRIPTION:Nuclear Structure of the Heaviest Elements – Investigated at SHIP - GSI\nBesides synthesizing new elements understanding the nuclear s tructure of heaviest nuclei is presently the main challenge of experimenta l and theoretical investigations concerning the field of Superheavy Elemen ts (SHE). \nAt GSI Darmstadt an extensive program on nuclear structure inv estigations by means of alpha-gamma– or alpha-conversion-electron- spect roscopy of nuclei collected in the focal plane of the velocity filter SHIP has been started about a decade ago.

However\, in the last several decades it has p rovided the most reliable way of calculating many nuclear properties globa lly for nuclides across the nuclear chart and for modeling basic propertie s of unknown nuclei such as superheavy nuclei or very neutron-rich nuclei. I will briefly describe the main features of the model and then show how our last mass table\, FRDM (1992)\, compares to a variety of nuclear-struc ture data\, and also discuss how HFB models compare these data. I will the n give a preview of our first mass-table revision in 20 years\, FRDM(2012) \, and the improvements relative to FRDM(1992). I will pay particular atte ntion to the results for superheavy nuclei. The macroscopic-microscopic me thod is also successfully applied to nuclear fission\, where HFB models ha ve significant problems\, inherent to the use constraints in such calculat ions. I will also discuss some new results from our fission work.\n\nhttp: //indico.cern.ch/conferenceDisplay.py?confId=186628 LOCATION:CERN 26-1-022 URL:http://indico.cern.ch/conferenceDisplay.py?confId=186628 END:VEVENT BEGIN:VEVENT SUMMARY:Lecture series on heavy and super heavy elements (3/3) DTSTART;VALUE=DATE-TIME:20120511T120000Z DTEND;VALUE=DATE-TIME:20120511T130000Z DTSTAMP;VALUE=DATE-TIME:20130518T192229Z UID:indico-event-186629@cern.ch DESCRIPTION:Nuclear Chemistry of the Heaviest Elements at JAEA\n Studies o n the chemical properties of the heaviest elements offer unique opportunit ies to obtain information about trends in the periodic table of the elemen ts at the limits of nuclear stability\, and to assess the magnitude of the influence of relativistic effects on chemical properties. From the calcul ations of electron configurations of heavier elements\, it is predicted th at sudden changes in the structure of electron shells may appear due to re lativistic effects which originate from the increasingly strong Coulomb fi eld of the highly charged atomic nucleus. Thus\, it is expected that heavi er elements show a drastic rearrangement of electrons in their atomic grou nd states\, and\, as electron configurations are responsible for chemical behavior of elements\, such relativistic effects can lead to surprising ch emical properties. Increasing deviations from the periodicity of chemical properties based on extrapolation from lighter homologues in the periodic table are consequently predicted.\n\n The heaviest elements must be produc ed at an accelerator using reactions of heavy-ion beams with heavy target materials and must be identified by measurement of their decay or that of their known daughter nuclei with unambiguous detection techniques. Both ha lf-lives and production rates of nuclides of heavier elements are rapidly decreasing\, and so each atom produced decays before a new atom is synthes ized. This means any chemistry to be performed must be done on an "atom-at -a-time" basis. \n\n To verify experimentally the influence of relativisti c effects of electron shell structure\, we are studying chemical propertie s of the heaviest elements\, rutherfordium (Rf: element 104)\, 261Rf (T1/2 = 68 s) and dubnium (Db: element 105)\, 262Db (T1/2 = 34 s) that were pro duced via the reactions of 248Cm(18O\, 5n) and 248Cm(19F\, 5n)\, respectiv ely\, using the JAEA tandem accelerator. In the seminar\, chemical studies of Rf and Db at JAEA are reviewed. Then\, we briefly introduce recent ele ctrochemical studies of the heaviest elements on an atom-at-a-time scale.  \n\nhttp://indico.cern.ch/conferenceDisplay.py?confId=186629 LOCATION:CERN 26-1-022 URL:http://indico.cern.ch/conferenceDisplay.py?confId=186629 END:VEVENT BEGIN:VEVENT SUMMARY:Quadrupole-octupole deformations and high-K isomeric states in hea vy nuclei DTSTART;VALUE=DATE-TIME:20120516T123000Z DTEND;VALUE=DATE-TIME:20120516T133000Z DTSTAMP;VALUE=DATE-TIME:20130518T192229Z UID:indico-event-186626@cern.ch DESCRIPTION:The manifestation of complex quadrupole-octupole shapes in ato mic nuclei leads to variety of specific phenomena and effects in their col lective and single particle (s.p.) motions\, such as the appearance of alt ernating-parity bands in even-even nuclei as well as quasi parity-doublet sequences and mixed-parity s.p. states in odd-mass nuclei. After a brief o verview of these phenomena and their description within a recently develop ed model formalism [1]-[3]\, the influence of the quadrupole-octupole defo rmations on the formation and the magnetic properties of high-K isomeric s tates in even-even nuclei will be discussed. Results of a recent study [4] of two-quasiparticle (2qp) isomeric states within a reflection-asymmetric deformed shell model with pairing correlations will be presented. Within this framework the behaviour of 2qp energies and magnetic dipole moments i s examined over a wide range in the plane of quadrupole and octupole defor mations [4]. The effect of the octupole deformation on the s.p. orbitals w hich form the isomeric state as well as on the respective 2qp energy will be demonstrated. It will be shown that in most of the considered nuclei th e magnetic moments of the two-quasiparticle isomeric states exhibit a pron ounced sensitivity to the octupole deformation. This result may suggest th e need of detailed experimental measurements of magnetic moments in heavy deformed nuclei.\n[1] N. Minkov\, P. Yotov\, S. Drenska and W. Scheid\, J. Phys.

One way to look for such rare ev ents is to set up large area detector arrays at high mountain altitudes. A n ideal choice of detector for such a setup would be solid state nuclear t rack detectors (SSNTDs)\, as they do not require power for their operation and also due to their ruggedness and existence of natural thresholds for registration. Use of SSNTDs in charged particle detection is a well establ ished method. But none of widely used standard SSNTDs (e.g. CR-39\, Lexan) is suitable as a detector for rare event search in cosmic rays because of their low detection thresholds\, which will lead to the recording of a hu ge low-Z background. So a commercially available polymer\, identified as p olyethylene terephthalate (PET)\, was investigated for its suitability as an SSNTD. PET was found to have a higher detection threshold compared to o ther standard SSNTDs. Systematic studies were carried out to characterize and calibrate PET by determining its ideal etching condition and also its charge response to beams of known energies of 16O\, 32S\, 56Fe ions from pelletron accelerator at IUAC\, New Delhi\, India\; 129Xe\, 78Kr\, 49Ti i ons from REX-ISOLDE at CERN\, Geneva\, Switzerland\; 238U from GSI\, Darm stadt\, Germany and also to fission fragments from natural radioactive sou rces. In addition\, pilot studies were carried out in which PET films were given open air exposures at high altitude locations like Darjeeling (2200 m)\, Ooty (2200m) and Hanle (4500m). The results of all these studies firm ly establish PET as an SSNTD with a detection threshold higher than other standard SSNTDs and the ability to eliminate the dominant low Z background makes PET particularly suitable as a detector for rare event search in co smic rays. \n\nhttp://indico.cern.ch/conferenceDisplay.py?confId=195216 LOCATION:CERN 26-1-022 URL:http://indico.cern.ch/conferenceDisplay.py?confId=195216 END:VEVENT BEGIN:VEVENT SUMMARY:Study of nuclear excited states through quantised angular momentum DTSTART;VALUE=DATE-TIME:20120622T090000Z DTEND;VALUE=DATE-TIME:20120622T094000Z DTSTAMP;VALUE=DATE-TIME:20130518T192229Z UID:indico-event-195696@cern.ch DESCRIPTION:The study of yrast states\, a group of lowest energy states fo r given angular momentum\, has been a primary interest to nuclear structu re physics since the 1970s\, when “backbending” was discovered as a po ssible phase transition phenomenon in nuclear finite many-body systems. Nu clear rotation is regarded to have a role analogous to a “magnetic fiel d” in triggering structural changes. Multi-quasiparticle states and rot ational alignment were intensively investigated to provide a physical inte rpretation of the transition. After 2000\, more exotic interpretations we re proposed in addition to these conventional ideas. The best known case i s “nuclear chiral rotation”. As a possible configuration\, angular mo mentum vectors for valence protons\, valence neutrons and collective rota tion of the core all point in different directions to produce the nuclear chirality. However\, the present model for nuclear chirality is based on a static and classical model\, where angular momentum is not quantised. I t is thus interesting to know whether nuclear chirality can survive quantu m fluctuations\, which counteract to destabilize the chiral configuration.  One can study such exotic nuclear rotations with quantised spin by means of quantum number projection methods. I have recently derived a new form ula to help carrying out the relevant calculations using these methods. I  would like to explain how helpful the formula is in order to understand excited states at high angular momentum\, which is quantised.\n\nhttp://i ndico.cern.ch/conferenceDisplay.py?confId=195696 LOCATION:CERN 26-1-022 URL:http://indico.cern.ch/conferenceDisplay.py?confId=195696 END:VEVENT BEGIN:VEVENT SUMMARY:The power of a T-REX with one MINIBALL - A low energy transfer stu dy of 10\,11\,12Be DTSTART;VALUE=DATE-TIME:20120704T123000Z DTEND;VALUE=DATE-TIME:20120704T131000Z DTSTAMP;VALUE=DATE-TIME:20130518T192229Z UID:indico-event-197671@cern.ch DESCRIPTION:\n Low energy transfer experiments are ideal to probe single p article excitations in nuclei\, and thereby study the shell evolution.

The aim was to study the mixing of the p- and the sd-shell in both 11Be and 12Be\, leading to the invers ion of states in the prior and the breaking of the N = 8 magic number in the latter. The analysis showed furthermore interesting effects in the el astic scattering of 11Be on light targets. Effects\, presumably caused by the halo structure of 11Be.\n\n The experiment was performed at REX-ISOLD E using the T-REX and MINIBALL setup for charged particle and gamma detec tion.

Furthermore decay studies of the long lived 0+_2 isomer and the lowest resonance in 12Be were performed using the MINIBALL’s germanium detectors for both gamma and neutron identification. The large angular co verage of the T-REX\, from 8 to 150 degrees\, along with the light partic les in the reaction\, enabled a study of the structure of the beam\, whic h help improved the resolution of the calculated excitation spectra.\n\n T he focus of the talk will be on the analysis of the experimental data\, in cluding the beam diagnostic and the identification of the individual react ions. A short introduction to neutron rich beryllium isotopes and transfe r reaction will be given in the beginning\, and the final part of the tal k will be on the theoretical interpretations of the data.\n\nhttp://indic o.cern.ch/conferenceDisplay.py?confId=197671 LOCATION:CERN 26-1-0022 URL:http://indico.cern.ch/conferenceDisplay.py?confId=197671 END:VEVENT BEGIN:VEVENT SUMMARY:Lectures on ab initio methods for nuclear physics (1/2) DTSTART;VALUE=DATE-TIME:20120709T090000Z DTEND;VALUE=DATE-TIME:20120709T100000Z DTSTAMP;VALUE=DATE-TIME:20130518T192229Z UID:indico-event-197778@cern.ch DESCRIPTION:\nThe fundamental description of both structural properties an d reactions of light nuclei in terms of constituent protons and neutrons i nteracting through nucleon-nucleon and three-nucleon forces is a long-soug ht goal of nuclear theory.

Their capability of giving access to various observ ables and their selective nature\, for instance\, in populating a specific state of interest\, are instrumental in enhancing our view of the subatom ic world. Experimentally\, an essential element to ensure these qualities – versatility and selectivity – is reaction targets. In the past deca de\, reaction studies using radioactive beams have been growing in importa nce as a probe of structures or reaction dynamics of unstable nuclei\, but at the same time it has been a big experimental challenge. The critical b ottle neck is target thickness. A thin target is necessary to detect low e nergy ions from collision between a heavy ion beam and a light ion target\ , while it limits luminosity and thus narrows down the path to rarer proce sses or more exotic nuclei. A time projection chamber\, AT-TPC\, currently under development at the National Superconducting Cyclotron Laboratory (N SCL)\, Michigan State University\, is meant to provide an ‘active target ’ for high resolution and efficient reaction studies at the future re-ac celerated radioactive beam facility of the NSCL. The defining feature of t his time projection chamber is its tracking gas medium simultaneously acti ng as a reaction target\, which enables us to measure trajectories as well as energy losses inside the reaction target\, thus making it possible to increase the target thickness with retaining the quality of ion detection. To study feasibility of envisioned detector technologies as well as to pr oduce scientific results at early stages of the project\, a half scale pro totype was constructed and commissioned in 2011. Two radioactive beam expe riments were performed at the Twinsol facility at the University of Notre Dame. In this talk\, the current status of the AT-TPC project will be pres ented with a focus on the prototype and the experiments at Notre Dame.\n\n http://indico.cern.ch/conferenceDisplay.py?confId=197680 LOCATION:CERN 26-1-0022 URL:http://indico.cern.ch/conferenceDisplay.py?confId=197680 END:VEVENT BEGIN:VEVENT SUMMARY:Study of the reaction of astrophysical interest 60Fe(n\,γ)61Fe vi a (d\,pγ) transfer reaction DTSTART;VALUE=DATE-TIME:20120725T123000Z DTEND;VALUE=DATE-TIME:20120725T131000Z DTSTAMP;VALUE=DATE-TIME:20130518T192229Z UID:indico-event-201642@cern.ch DESCRIPTION:60Fe is of special interest in nuclear astrophysics. Indeed th e recent observations of 60Fe caracteristic gamma-ray lines by the RHESSI and INTEGRAL spacecrafts allowed to measure the total flux of 60Fe over the Galaxy. Moreover the observation in presolar grains of an excess of 60 Ni\, the daughter nuclei of 60Fe\, gives constraints on the conditions of formation of the early solar system. However\, the cross-sections of som e reactions involved in 60Fe nucleosynthesis and included to stellar model s are still uncertain. The destruction reaction of 60Fe\, 60Fe(n\,γ)61Fe \, is one of them. The total crosssection can be separated into two contr ibutions: the direct one\, involving states below the neutron separation threshold of 61Fe\, and the resonant one.\n 60Fe(n\,γ)61Fe reaction was s tudied via the d(60Fe\,pγ) transfer reaction at LISE/GANIL\, with an exp erimental setup made of two beam tracking detectors\, four MUST2 telescope s and four EXOGAM clovers. 61Fe spectroscopy was improved in order to eva luate the direct capture part of 60Fe(n\,γ)61Fe reaction cross-section. DWBA analysis of experimental proton differential crosssections\, which a llowed to extract orbital angular momentum and spectroscopic factors of th e populated states of 61Fe below the neutron threshold\, will be presente d. Finally\, our experimental results will be compared to shell-model cal culations.\n\nhttp://indico.cern.ch/conferenceDisplay.py?confId=201642 LOCATION:CERN 26-1-022 URL:http://indico.cern.ch/conferenceDisplay.py?confId=201642 END:VEVENT BEGIN:VEVENT SUMMARY:Fusion and Transfer Reactions in Heavy Collision Systems with Stab le and Radioactive Beams DTSTART;VALUE=DATE-TIME:20120912T123000Z DTEND;VALUE=DATE-TIME:20120912T131000Z DTSTAMP;VALUE=DATE-TIME:20130518T192229Z UID:indico-event-205076@cern.ch DESCRIPTION:At GSI Darmstadt we perform experiments on fusion and transfer reactions in very heavy collision systems like e.g. Ca+Pb up to U+U at be am energies below and around the Coulomb barrier (≈ 4 to 6 MeV/u). A mai n goal is the synthesis and investigation of heavy and superheavy nuclei w hich are produced in fusion reactions at the velocity filter SHIP. Additio nally\, we perform studies of the fusion process in very heavy systems wha t is still a hardly understood process from experimental as well as theore tical point of view. According to some theoretical models\, fusion and nuc leon transfer are regarded as closely related processes in the sense that transfer is assumed as first step to fusion of heavy systems. In this cont ext we study transfer reactions in the heaviest systems at SHIP and other setups. On the other hand\, we investigate transfer reactions also as a me ans to synthesize new exotic heavy isotopes which are not reachable in oth er reactions.\nFor the future\, when appropriate facilities become availab le\, we plan to extend our experiments to reactions with radioactive beams which promise for certain reactions many orders of magnitude larger cross -sections and accessibility to isotopes which cannot be reached with stabl e beams. This presentation will give an overview on our present activities \, possible future experiments with radioactive beams and appropriate expe rimental setups.\n\nhttp://indico.cern.ch/conferenceDisplay.py?confId=2050 76 LOCATION:CERN 26-1-0022 URL:http://indico.cern.ch/conferenceDisplay.py?confId=205076 END:VEVENT BEGIN:VEVENT SUMMARY:Superallowed Fermi Beta Decay Studies at TRIUMF-ISAC DTSTART;VALUE=DATE-TIME:20120919T123000Z DTEND;VALUE=DATE-TIME:20120919T131000Z DTSTAMP;VALUE=DATE-TIME:20130518T192229Z UID:indico-event-208546@cern.ch DESCRIPTION:A program of high-precision superallowed Fermi beta decay stud ies is currently being carried out at the Isotope Separator and Accelerato r (ISAC) radioactive ion beam facility at TRIUMF\, Canada's national labor atory for nuclear and particle physics research.

Especially on the neutron deficient side the limit of nuclear stability  the proton drip-line  is approached and in many cases crossed for almost all elements up to thorium.

For instance\, the study of a pure Gamow-Teller (GT) transition enable s to probe tensor-type couplings while a pure Fermi (F) transition is sens itive to scalar-type interactions. Moreover\, in the case of mirror transi tions\, a precise measurement of a also allows the determination of the mi xing ratio between the GT and F contributions. This constitutes an importa nt input for the database of nuclear mirror transitions\, leading to the e xtraction of the Vud\nelement of the CKM matrix. In a beta-neutrino correl ation measurement\, the most relevant observable is the energy of the\nrec oiling daughter nucleus. In the LPCTrap device\, the radioactive nuclei ar e confined in a Paul trap\, allowing the detection of the recoil ions in c oincidence with the beta particles. The set-up is\npresently installed at LIRAT\, the low energy beam line of the SPIRAL facility at GANIL. The firs t studied case is the 6He pure GT decay. A relative statistical precision of 0.5% has been reached on the correlation parameter. Particular attentio n is continuously being devoted to the study of systematic effects. For in stance\, the detection set-up is sensitive to the charge state distributio ns of the recoiling ions\, allowing the determination of the shake-off pro babilities in the decay of 1+ ions\, which have never been measured until now.\nAs the Paul trap enables to confine any radioactive species\, an exp eriment with 35Ar\, which essentially decays through a mirror transition w ith a large Fermi component (>90%)\, has also been performed\, and a stati stical precision of 0.2% is expected on a.\nThese first experiments have c learly shown that LPCTrap is well suited for precise correlation measureme nts. A new experiment with 19Ne is accepted and it should be scheduled nex t year. The next step is a significant upgrade of the whole set-up to impr ove\, on one hand\, the statistical precision to the 0.1% level and\, on t he other hand\, to perform relevant experiments with the future radioactiv e beams soon available at GANIL in the framework of the UPGRADE of SPIRAL\ nproject\, and later at the SPIRAL2/DESIR facility.\nThese different aspec ts will be discussed during the seminar.\n\nhttp://indico.cern.ch/conferen ceDisplay.py?confId=210982 LOCATION:CERN 26-1-022 URL:http://indico.cern.ch/conferenceDisplay.py?confId=210982 END:VEVENT BEGIN:VEVENT SUMMARY:A laser trap for parity non-conservation measurements in francium at TRIUMF DTSTART;VALUE=DATE-TIME:20121115T100000Z DTEND;VALUE=DATE-TIME:20121115T110000Z DTSTAMP;VALUE=DATE-TIME:20130518T192229Z UID:indico-event-217022@cern.ch DESCRIPTION:A francium trapping facility is under development for parity v iolation\nmeasurements in francium.

The so-called "Island of stability of s uperheavy elements" is still a recurring pattern in current theoretical ap proaches used to describe nuclear ground state phenomena. \nExperimentalis ts have embarked into the uncharted seas "north-east" of the heaviest nucl ei found on earth and discovered nuclei with finite lifetimes\, often even ranging up to seconds\, minutes\, or even longer for elements with Z up t o 112\, 114\, or even 116\, suggesting that the Island of Stability may in fact be connected to the mainland. Element 116 is the heaviest element of ficially recognized by the IUPAC\, with some heavier ones being claimed in the literature. Half-lives start to increase again in the heaviest nuclei \, especially as more and more neutron-rich isotopes are studied\, validat ing the concept of the Island of Stability and suggesting that we have rea ched its shoreline.\nAt GSI Darmstadt\, studies of superheavy elements are one of the pillars of the research program and exploit a unique combinati on of experimental facilities that allows addressing key questions in SHE research\, including i) the synthesis of the heaviest elements\, ii) nucle ar reaction studies\, iii) nuclear structure investigations with a focus o n nuclear isomerism in deformed nuclei with Z~100-110\, iv) the direct ide ntification of the atomic number of nuclides produced in 48Ca-induced fusi on reactions with actinide targets\, v) chemical properties of the transac tinide elements\, and vi) direct mass measurements beyond fermium.\nIn my talk\, I will introduce the field of superheavy element research in genera l and then give a few examples on recent experiments\, focusing on the sea rch for new elements beyond the heaviest claimed element with Z=118.\n\nht tp://indico.cern.ch/conferenceDisplay.py?confId=210988 LOCATION:CERN 26-1-022 URL:http://indico.cern.ch/conferenceDisplay.py?confId=210988 END:VEVENT BEGIN:VEVENT SUMMARY:The Fukushima accident: from the tsunami to radiation monitoring a cross the globe DTSTART;VALUE=DATE-TIME:20121212T133000Z DTEND;VALUE=DATE-TIME:20121212T143000Z DTSTAMP;VALUE=DATE-TIME:20130518T192229Z UID:indico-event-209887@cern.ch DESCRIPTION:After the devastating earthquake and tsunami in Japan on March 11\, 2011\, and the ensuing damage to the Fukushima Dai-ichi nuclear reac tor complex a worldwide effort began to monitor the released radioactivity as it spread around the globe.\nAt the University of Washington\, Seattle \, we started a monitoring program for airborne radioactivity 5 days after the earthquake and only a day later started to detect the first radionucl ides that were released at the Fukushima plant.

Understanding the Weak axial curren t is important for many issues\, for example\, stellar nucleosynthesis\, d ouble-beta decay\, and tests of nuclear wave functions.\nThe radioisotope 6He is a particularly attractive system for weak interaction studies due t o its half-life of approximately 807 ms\, its pure Gamow-Teller transition proceeding close to 100% to the ground state of 6Li and the fact that it is light enough to perform ab-initio calculations with precision.\nAt the University of Washington we developed a high-intensity source of 6He capab le of delivering ~10^9 atoms/s to a low-background experimental area. Usin g this intensity we recently measured the half-life to a precision of 3x10 ^-4 resolving a long standing discrepancy. This provides a solid basis for comparison with ab-initio calculations modeling the weak interaction in t he nucleus.\nCurrently\, we are setting up a trapping system consisting of a Zeeman slower and a magneto-optical trap (an additional dipole trap wil l be added later) and the necessary detectors to perform a measurement of the beta-neutrino angular correlation. This will allow us to search for ne w physics in the form of tensor contributions to the well established vect or and axial-vector structure of the weak interaction.\n\nhttp://indico.ce rn.ch/conferenceDisplay.py?confId=223370 LOCATION:CERN 26-1-022 URL:http://indico.cern.ch/conferenceDisplay.py?confId=223370 END:VEVENT BEGIN:VEVENT SUMMARY:Proton/Antiproton Magnetic Moments and the Hyperfine Structure of Antihydrogen DTSTART;VALUE=DATE-TIME:20130207T133000Z DTEND;VALUE=DATE-TIME:20130207T143000Z DTSTAMP;VALUE=DATE-TIME:20130518T192229Z UID:indico-event-223265@cern.ch DESCRIPTION:The precision spectroscopy of simple antimatter systems and th e comparison to their matter counterparts contributes to our understanding of the matter/antimatter asymmetry which is observed on cosmological scal es. Specifically interesting are experimental studies of systems at an ult ra-low absolute energy scale\, as the comparison of the magnetic moment of the proton and the antiproton\, or the hyperfine structure of hydrogen an d antihydrogen. In 2011 we observed for the first time spin flips with a s ingle trapped proton\, which is a major step towards a high precision meas urement of the particle’s magnetic moment. Based on these results measur ements at a precision close to the ppm-level were performed in a Penning t rap with a superimposed inhomogeneous magnetic field. Applying the method to a single antiproton\, the particle’s magnetic moment can be improved now by three orders of magnitude. Recently the ATRAP collaboration reporte d on a first determination of the magnetic moment of the antiproton at a l evel of 4.4ppm. Using a double-Penning trap scheme the ATRAP collaboration as well as the BASE collaboration intend to improve this precision down t o the ppb-level\, at least. \nAnother experiment which investigates the p roperties of antimatter at a comparable energy scale as the one described above is the precision comparison of the hyperfine structure of hydrogen a nd antihydrogen. Antihydrogen was recently produced in a so-called CUSP\, which is utilized to produce a polarized anti-atomic beam.

The nuclei of interest were produced via m ulti-nucleon transfer reactions in inverse kinematics using a 238U beam at an energy of ~16% above the Coulomb barrier. The γ-rays emitted at the t arget point were measured with the EXOGAM array and the delayed γ-rays we re measured in the focal plane of the spectrometer with four additionnal g ermaniums detectors. I will report first on the recent spectroscopy measur ement in 68Ni and neutron-rich Co isotopes and second on lifetime measurem ents in the very neutron-rich Zn\, Co and Fe isotopes using the plunger te chnique. Large scale shell model as well as QRPA calculations have been ca rried out and they all are consistent with the earlier Hartree-Fock-Bogoli ubov predictions using the Gogny D1S effective interaction indicating a po ssible shape coexistence scenario involving a highly deformed state at low energy.\n\nhttp://indico.cern.ch/conferenceDisplay.py?confId=223267 LOCATION:CERN 26-1-022 URL:http://indico.cern.ch/conferenceDisplay.py?confId=223267 END:VEVENT BEGIN:VEVENT SUMMARY:CRIS: Studying the neutron deficient francium isotopes with laser and decay spectroscopy DTSTART;VALUE=DATE-TIME:20130228T133000Z DTEND;VALUE=DATE-TIME:20130228T143000Z DTSTAMP;VALUE=DATE-TIME:20130518T192229Z UID:indico-event-223379@cern.ch DESCRIPTION:The Collinear Resonant Ionization Spectroscopy (CRIS) experime nt at ISOLDE\, CERN uses laser radiation to stepwise excite and ionize an atomic beam for the purpose of ultra-sensitive detection of rare isotopes\ , and hyperfine structure measurements. The technique also offers the abil ity to purify an ion beam that is heavily contaminated with radioactive is obars\, including the ground state of an isotope from its isomer\, allowin g sensitive secondary experiments to be performed.\n\nA new program using the CRIS technique to select only nuclear isomeric states for decay spectr oscopy commenced in 2011. The isomeric ion beam is selected using a resona nce of its hyperfine structure\, where it is deflected to a decay spectros copy station (DSS). This consists of a rotating wheel implantation system for alpha and beta decay spectroscopy\, and up to three germanium detector s around the implantation site for gamma-ray detection.\n\nLaser spectrosc opy provides a measurement of the spin of the ground and isomeric states i n the parent nucleus\, while the level structure of the daughter nucleus c omes from the complementary decay spectroscopy\, thus providing a wealth o f information on the isotope under investigation.\n\nResonant ionization l aser spectroscopy and the new technique of laser assisted decay spectrosco py have recently been performed at the CRIS beam line on the neutron-defic ient francium isotopes. Here the latest results from our experimental camp aign will be presented\, alongside an overview of the CRIS beam line and t he DSS.\n\nhttp://indico.cern.ch/conferenceDisplay.py?confId=223379 LOCATION:CERN 26-1-022 URL:http://indico.cern.ch/conferenceDisplay.py?confId=223379 END:VEVENT BEGIN:VEVENT SUMMARY:High precision mass measurements and in trap-decay spectroscopy of rare isotopes at TITAN / TRIUMF DTSTART;VALUE=DATE-TIME:20130307T133000Z DTEND;VALUE=DATE-TIME:20130307T143000Z DTSTAMP;VALUE=DATE-TIME:20130518T192229Z UID:indico-event-227906@cern.ch DESCRIPTION:Atomic masses of rare isotopes continue to be a fundamental in gredient for studies of nuclear structure\, nuclear astrophysics\, and fun damental symmetries. In the endeavor to explore the nuclear mass surface t owards the limits of nuclear existence\, TRIUMF’s Ion Trap for Atomic an d Nuclear Science (TITAN) has pioneered Penning trap mass spectrometry alo ng two aspects: Firstly\, it is uniquely capable to handle very short live d nuclides with half-lives even below 10 ms [1]. Secondly\, it is pushing on the precision frontier by utilizing an electron beam ion trap to breed short-lived nuclides delivered from ISAC / TRIUMF to a higher charge state . The precision of the mass measurement in a Penning trap is thereby boost ed by a factor identical to the charge state q of the ion. In combination with advanced excitation schemes such as the recently introduced Ramsey te chnique [3]\, this novel approach for rare isotopes opens the path towards gains of 1-2 orders of magnitude in experimental precision. \nRecently\, these unique experimental capabilities at a radioactive ion beam facility allowed TITAN to make contributions in a variety of physics questions. The se range from nuclear structure topics as neutron-rich Ca-isotopes as a su perb testing ground for 3-body forces [4] or shell gaps in the island of i nversion [5]\, over superallowed nuclear beta decays to determine Vud of t he Cabibbo–Kobayashi–Maskawa matrix [2]\, to solar neutrino physics [6 ]. For the latter\, the energy threshold (or Q-value) of 71Ga(ν\,e−) 71 Ge was determined accurately using ions with up to q=22+. Previously this Q-value represented a nuclear physics uncertainty relevant for the discrep ancy observed in the SAGE and GALLEX neutrino calibration measurements [7] . \nIn addition to the mass measurement program\, TITAN is developing a no vel method for in-trap decay spectroscopy to determine very weak electron capture branching ratios as relevant in the context of nuclear matrix elem ents of 2νββ- decays [8]. This talk will provide an overview over the T ITAN facility and a summary of recent results.\n\n[1] M. Smith et al.\, Ph ys. Rev. Lett. 101\, 202501 (2008)\n[2] S. Ettenauer et al.\, Phys. Rev.

In this talk I will show how recent mass measurements have a direct impact on the equation of state (EOS) of the outer crust of neutron stars and the low-density supernova equation of state. At high densities\ , one of the major uncertainties of the EOS comes from the symmetry energy . Also here\, systematics from nuclear binding energies lead to an importa nt constraint. Complementary information comes from recent theoretical res ults for the neutron matter equation of state and from astronomical observ ations of neutron stars. I will show how these constraints\, if combined t ogether\, allow to rule out some commonly used EOSs and limit the possible range of masses and radii of neutron stars. In a second example I will di scuss how these constraints affect the scenario of black hole formation in so-called failed core-collapse supernovae.\n\nhttp://indico.cern.ch/confe renceDisplay.py?confId=234459 LOCATION:CERN 26-1-022 URL:http://indico.cern.ch/conferenceDisplay.py?confId=234459 END:VEVENT BEGIN:VEVENT SUMMARY:Statistical tools for nuclear experiments (1/4) DTSTART;VALUE=DATE-TIME:20130318T093000Z DTEND;VALUE=DATE-TIME:20130318T103000Z DTSTAMP;VALUE=DATE-TIME:20130518T192229Z UID:indico-event-218651@cern.ch DESCRIPTION:Essentially all experiments in nuclear physics today involve s tatistical methods during analysis of the obtained data.

In particular\, the half-life and decay modes of these isotopes are observed in the KULeuven Windmill se tup or the CRIS Decay Spectroscopy Station\, both equipped with 20ug/cm2 f oils from the GSI Target Laboratory.

Electrical and magnetic properties and molecular functionalization strongl y depend on surface and interface nanoscale interactions\, where new physi cal models should apply aiming their understanding and control.\nWhere the human imagination fails\, Nature surprises\; such is the case of the Merm in-Wagner Theorem\, for many years supporting the idea that a two-dimensio nal structure would be unstable and thus impossible to obtain\, while the contrary was proven to be true by A. Geim and K. Novoselov in 2004 when th ey isolated successfully graphite monolayers by a method of mechanical exf oliation\, hence\, the first 2D material was found\, the graphene. This on e-atom-thick manufacture of carbon\, uniquely\, as well being hidden behin d the scratching of a pencil-also discovered in England for over 400 years \, combines extreme mechanical strength\, exceptionally high electronic an d thermal conductivities\, as well as many other supreme properties\, all of which make it highly attractive for numerous applications.\nIn the pres ent work - still debuting experiments – we investigate the mechanisms of adhesion of ad-atoms on the surface\, alone or when forming clusters\, pr eferably in regions of structural defects (of different kinds)\, their cap ture processes\, adsorption and migration of atoms. The aim is to investig ate electronic\, magnetic or catalytic properties. Understanding how the a dsorption could be controlled would contribute to the development of innov ative devices based on graphene. Experimental works are accompanied by the ory and computational models generally based on density functional theory and/or molecular dynamics calculations\, providing an important support fo r studying the electronic properties. In this context\, where theory was f irst denying that 2D materials could exist\, now theory try to repent itse lf by a multitude of enthusiastic predictions\, hoping for new discoveries of unique properties\, being a major driver of nanotechnology for the dev elopment of devices such as quantum detectors of single molecules with app lications in catalysis and nucleation of clusters in nanostructures\, ball istic transistors and spintronic devices.\nOur experimental observables ar e the hyperfine parameters of add-atoms on graphene\, measured with the nu clear spectroscopy PAC (Perturbed Angular Correlations) technique. PAC all ows to probe at the atomic scale the add-atoms interactions without interf ering with the graphene electronic structure\, thereby providing unique in formation\, which is impossible to obtain by electron spectroscopy and ele ctron microscopy techniques such as\, AFM or STM\, not exempted from inter actions between the tip and the surface test or ad-atoms therein. By PAC m easurements it can be determined the electric field gradient (EFG) and mag netic hyperfine field (MHF) at atomic scale\, electronic structure and mag netic environment of ad-atoms. The EFG provides structural information\, l ocation of the probe\, stability\, and bond (ionic\, covalent bonding\, va n der Waals). The MHF translates properties correlated with the electronic spin configuration.\nWe intend\, in this brief presentation\, to present the first results of the hyperfine parameters in graphene on different sub strates\, obtained by PAC measurements\, using as probes the radioactive i sotopes 111mCd\, 111In and 199mHg. These are preliminary results of a larg e portfolio of experiments and ideas\, with envisaged complementary studie s of other experimental techniques the whole accompanied by the theoretica l background based on ab initio simulations\, aiming to achieve consistent models.\n\nhttp://indico.cern.ch/conferenceDisplay.py?confId=244024 LOCATION:CERN 26-1-022 URL:http://indico.cern.ch/conferenceDisplay.py?confId=244024 END:VEVENT BEGIN:VEVENT SUMMARY:Introducing Authorea\, an online collaborative platform for creati ng and sharing dynamic articles that are built for the modern web DTSTART;VALUE=DATE-TIME:20130418T123000Z DTEND;VALUE=DATE-TIME:20130418T133000Z DTSTAMP;VALUE=DATE-TIME:20130518T192229Z UID:indico-event-241360@cern.ch DESCRIPTION:Did you ever wish collaborating on scholarly articles was easy ?

The overarching objective of the work is to advances the theory of deuteron stripping reactions leadin g to bound states and resonances\, utilizing the state-of-the-art theoreti cal and computational technology.

This work identifies what model-in dependent spectroscopic information can be extracted from analysis of tran sfer nuclear reactions.\n2. New theory of deuteron stripping based on the surface integral formalism\, generalized R-matrix and CDCC was formulated in [2]. It allows us to parameterize deuteron stripping amplitudes in term s of the\nsame observables as in the conventional R matrix. In particular\ , for stripping to resonance states partial resonance widths can be extrac ted from the deuteron stripping in the same way as in the traditional R-ma trix method for resonance scattering.\n3. The developed new theory provide s a new tool in using deuteron stripping reactions as indirect methods in nuclear astrophysics: ANC and Trojan Horse methods [3].

There exists strong circumsta ntial evidence\, however\, that some combinations of protons and neutrons will give rise to octupole deformation\, or a reflection-asymmetric pear-l ike shape.\n\nIt can be expected that the actinides will possess the stron gest octupole collectivity\, leading to the largest array of experimental evidence so far. But there's a problem… the nuclei in this region of the chart are unstable. This means that direct information on the electric-oc tupole transitions connecting excited states in these nuclei have not been accessible. So far\, only 226Ra with its relatively long lifetime of 1600 years has had its octupole collectivity quantified.\n\nWith the advent of radioactive ion beams (RIBs) and in particular\, the ground-breaking abil ity to post-accelerate the heavy elements radon and radium at REX-ISOLDE\, we have recently overcome the challenges limiting our knowledge in this r egion. Coulomb excitation was successfully performed on 220Rn and 224Ra an d the E1\, E2 and E3 matrix elements connecting the lowest energy states h ave been determined.\n\nIn this seminar I will review our current understa nding of octupole deformation in nuclei and discuss the results of these p ioneering experiments. The results are not only significant for nuclear st ructure\, but also on the search for atomic electric-dipole moments (EDMs) which are predicted to be enhanced by octupole deformation. The consequen ce of our results on on-going experiments looking for EDMs to test the Sta ndard Model will also be discussed.\n\nhttp://indico.cern.ch/conferenceDis play.py?confId=248506 LOCATION:CERN 26-1-022 URL:http://indico.cern.ch/conferenceDisplay.py?confId=248506 END:VEVENT END:VCALENDAR
