These nuclei are \nby-passed by the s- and r-pr ocess pathways. To date\, these nuclei have been \nobserved only in the so lar system. Understanding the synthesis of these p-process \nnuclei on the basis of astrophysical processes occurring outside the solar system\, \nl ike e.g. in exploding supernovae (SNII) or on He-accreting white dwarves w ith sub-\nChandrasekhar mass\, which are both thought to be the most possi ble p-process sites\, \nwill enable us not only to understand the nuclidic composition of the solar system \nbut also to further elucidate our funda mental picture of its creation. \n\nAbundance calculations of the p nuclei make an extensive use of the nuclear \nstatistical model for the calculat ion of the rates of an extended reaction network. \nComparison with (p\,ga mma) and/or (n\,gamma) cross section indicate that these rates \ncan be pr edicted within a factor of two. However\, some very scarce (alpha\,gamma) \ndata show that the reaction rates calculated using phenomenological alph a-particle \noptical potentials can be wrong by a factor of ten or more.

(Centro de Física Nuclear da Univers idade de Lisboa\, Portugal)\nStrontium-titanate is a perovskite ceramic ma terial\, which is of interest\, e.g.\, \nfor future devices based on metal -oxide Si heterostructures such as high-k field \neffect transistors. The electrical\, optical and magnetic properties of SrTiO3 can \nbe modified b y the incorporation of dopants. For instance\, transition metal doped \nSr TiO3 has been considered as a candidate for a room-temperature ferromagnet ic \nsemiconductor [1]. Ion implantation might thus represent an attractiv e approach for \ndoping\, especially in cases where the solubility of dopa nts is limited and they \ncannot be introduced during growth. However\, ve ry little is known about the \nfundamental question whether implants are i ncorporated on proper lattice sites in \nSrTiO3 (substitutional Sr\, subst itutional Ti and substitutional O sites\, regular \ninterstitial sites or randomly dispersed). This can be studied with the emission \nchannelling t echnique\, which unambiguously identifies and quantifies the impurity \nla ttice site location. \nResults for implanted 111Ag in SrTiO3 perovskite ar e reported to illustrate the EC \ntechnique capabilities. Electron channel ing patterns were measured around several \ncrystalline directions followi ng in-situ-vacuum annealing up to 900ºC. It is shown \nthat in the as-im planted state\, Ag occupies several lattice sites and upon \nannealing\, m ost of Ag goes to near-substitutional Sr sites [2]\, while for instance \n Fe is to a large extent incorporated on Ti substitutional sites.\nIn addit ion\, a short description of a new data readout technology for electron Si \npad detectors with a strong impact on the applications of the EC techni que will be \npresented. The new technology improves the detection efficie ncy of very low energy \nconversion electrons below 40keV\, and at the sam e time\, allows very high readout \ncount rates up to tens of kHz. These f acts will broaden the range of available \nelements for EC studies\, in pa rticular\, by using short-lived isotopes\, already next \nyear. Perspectiv es about the near future of the EC technique at ISOLDE-CERN will be \ngive n. \n[1] S.J. Pearton\, W.H. Heo\, M. Ivill\, D.P. Norton\, and T. Steiner \, Semicond.

Its measurement contributes to a \nvariety of f undamental studies including tests of the Standard Model and the weak \nin teraction. The limits of mass measurements of exotic nuclei have been exte nded \nconsiderably by improving and developing the Penning trap mass spec trometer ISOLTRAP \nat the ISOLDE facility at CERN. The mass resolving pow er of ISOLTRAP reaches 107 and \nthe uncertainty of the resulting mass val ues has been pushed down to 8*10-9. The \nmass is determined via a time-of -flight cyclotron resonance detection technique. To \nreduce the measureme nt uncertainty a number of improvements in ion detection and \ndata taking have been developed. One of these is the use of the Ramsey method\, i.e. \ntime separated oscillating fields\, for the excitation of the ions’ m otion. The \nadvantage of this method is a reduction of the line width of the resonance. In \naddition the weights of the individual frequency point s of the resonance curve are \nanalyzed\, which results in a step-size opt imization. The methods as well as the \nresults will be presented.\n\nhttp ://indico.cern.ch/contributionDisplay.py?contribId=48&sessionId=1&confId=3 28 LOCATION:CERN Council Chamber\, 503/1-001 URL:http://indico.cern.ch/contributionDisplay.py?contribId=48&sessionId=1& confId=328 END:VEVENT BEGIN:VEVENT SUMMARY:Proton induced thermal stress wave measurements for ISOLDE and CNG S DTSTART;VALUE=DATE-TIME:20060208T113500Z DTEND;VALUE=DATE-TIME:20060208T115500Z DTSTAMP;VALUE=DATE-TIME:20130523T122437Z UID:indico-contribution-328-49@cern.ch DESCRIPTION:Speakers: Mr. WILFINGER\, Roman (CERN)\n TBA\n\nhttp://indico .cern.ch/contributionDisplay.py?contribId=49&sessionId=10&confId=328 LOCATION:CERN Council Chamber\, 503/1-001 URL:http://indico.cern.ch/contributionDisplay.py?contribId=49&sessionId=10 &confId=328 END:VEVENT BEGIN:VEVENT SUMMARY:Moments and spins of neutron rich Mg isotopes: towards 33Mg DTSTART;VALUE=DATE-TIME:20060207T105500Z DTEND;VALUE=DATE-TIME:20060207T111500Z DTSTAMP;VALUE=DATE-TIME:20130523T122437Z UID:indico-contribution-328-46@cern.ch DESCRIPTION:Speakers: D. YORDANOV\, Deyan (IKS)\nOur research on the neutr on rich side of the Mg chain will be presented\, which is of \ninterest in the frame of understanding nuclear structure in the region of \nthe “Is land of inversion”. Nuclei around 32Mg exhibit properties in disagreemen t \nwith the standard shell model. Advanced modeling of the region require s experimental \ndata\, crucial parts of which are the nuclear moments dat a. The research taking place \nthe last years at the collinear laser spect roscopy setup COLLAPS at ISOLDE\, CERN has \nsignificantly contributed in this aspect. The obtained nuclear moments and hyperfine \nstructure of 27\ , 29\, 31Mg will be presented\, illustrating the actuality of the \ntechni que of nuclear magnetic resonance in combination with laser spectroscopy. \nInterpretation in the frame of the shell model will be given\, and in th e case of \n31Mg the results will be linked with a resent β – decay stu dy and discussed in the \nterms of particle – hole excitations over N=20 shell gap.

A broad range of \np hysical phenomena can be addressed by high-resolution in-beam γ-ray spect roscopy \nmeasurements with radioactive beams offered within the Rare ISot opes INvestigation \nat GSI (RISING) project. It combines the EUROBALL Ge- Cluster detectors\, the \nMINIBALL Ge detectors\, HECTOR-BaF detectors\, a nd the fragment separator FRS. The \nsecondary beams produced at relativis tic energies are used for Coulomb excitation \nor secondary fragmentation experiments to study projectile like nuclei by measuring \nde-excitation p hotons. Alternatively\, the relativistic radioactive beams are \nimplanted into a detector/stopper and their decay can be investigated\, or slowed \ ndown to the energies suited for the fusion or transfer reactions and a "c lassical" \nin-beam spectroscopy. \nFuture ideas born from the experience with the RISING project will lead to a new \ninstrumentation within NUSTA R at FAIR.

In compound semicond uctors\, large\nconcentrations of intrinsic point defects can be obtained by inducing slight\ndeviations from stoichiometry by exposing the respecti ve material to external vapor\npressures of one of its constituents.\nIn C dTe\, the diffusion of Ag was studied using the radiotracer 111-Ag implant ed into\ntypically 500 - 800 µm thick CdTe crystals [1] with surprising r esults. After\nimplantation of 111-Ag into the front side of a CdTe crysta l and a diffusion anneal\nunder vacuum\, the diffusion profile shows the e xpected ‘normal’behavior\, a\nmonotonously decreasing Ag concentration . But\, performing the diffusion anneal under\nexternal Cd pressure result s in a total different diffusion profile: two depletion\nlayers of about 3 00 µm width appear at both surfaces of the crystal. In contrast\,\nlayers of increased Ag concentration\, situated about 20 µm below each surface\ , with\nthe Ag concentration in the interior of the crystal being signific antly lower are\nobserved if the diffusion is performed under Te pressure. Since in normal diffusion\nexperiments the material flow has the inverse direction of the corresponding\nconcentration gradients\, these results ca n not be explained by simple diffusion\naccording to Fick´s laws. The obs erved new type of diffusion profiles can be\nunderstood in the framework o f a model based on defect reactions of the Ag dopant\nwith intrinsic defec ts [2]. The flux of the Ag atoms essentially is determined by its\ninterst itial fraction Agi while Ag atoms incorporated on substitutional Cd lattic e\nsites are immobile. It can be shown that the flux of Ag consists of two \ncontributions: i) a normal diffusion flux\, directed opposite to the gra dient of the\nAgi distribution and ii) a drift of the charged defects caus ed by the gradient of the\nFermi level\, which essentially follows the dis tribution of the intrinsic defects.\nMoreover\, the diffusion behavior of Ag can be manipulated by the presence of the\ngroup Ib elements Cu or Au. If Ag is diffused simultaneously with these elements a\nreplacement of Ag atoms in favor of Cu or Au takes place. After evaporating of 20 nm\nCu on the 111-Ag implanted side of a CdTe crystal and subsequent diffusion at 55 0 K\nfor 30 min nearly all Ag atoms are located within a thin layer of 10 μm beneath the\nback of the sample. This phenomenon can be explained usin g the model outlined before\nwhere Cu acts as a replacement for interstiti al Cd defects.\n\n[1] H. Wolf\, F. Wagner\, Th.

Measurements o n tellurium isotopes (Z = 52) can provide \nreliable information on the sh ape of nuclei\, structure of states\, and effects of \ndynamics. Indeed fr om A = 115 to 133\, all the odd-A Te isotopes exhibit an isomeric \nstate and the measurement of the isomeric shift gives us a direct indication of the \ninfluence of the neutron-core coupling on the nuclear deformation. M oreover the \ndetermination of the magnetic moments yields information on the structure of the \nstates. In particular the measurements on the neutr on-rich tellurium isotopes allow \nus to study the variation of the kink a t N = 82 approaching the proton magic number \nZ = 50.\nISOLDE offers the opportunity for studying the tellurium isotope series over a wide \nmass r ange\, from the nuclei located near the N = 66 neutron mid-shell to the ne utron-\nrich ones beyond the neutron shell closure at N = 82. In this cont ribution we will \npresent the laser spectroscopy experiment performed on the neutron-rich tellurium \nisotopes and the results obtained up to now. The neutron-rich Te isotopes have been \nproduced by the 238U fission indu ced by 1 GeV protons in a uranium carbide target \nassociated with a hot p lasma ion source. The laser spectroscopy measurements have \nbeen performe d on the 127-136Te ground states and on the 123\,125\,127\,129\,131\,133Te \nisomeric states using the COMPLIS (COllaboration for Measurements using a Pulsed \nLaser Ion Source) setup that allows resonance ionization spect roscopy (RIS) on laser-\ndesorbed atoms. To avoid direct and disturbing io nization of the isobars by the non-\nresonant step\, a three step process had to be used to ionize selectively the \ntellurium isotopes: 214.35\, 59 1.6 and 1064 nm. Spectroscopic information (isotope \nshift and hyperfine structure) has been obtained by scanning the first excitation \nstep (the 5p4 3P2  5p3 6s 3S1 optical transition at 214.35 nm) of the RIS process . \nThe analysis of the data is still in progress. However the   values obtained for \nthe even-even isotopes show that the kink at N = 82 remains in Te\, i. e. in an \nisotopic series with a proton number very cl ose to the magic number Z = 50.\n\nhttp://indico.cern.ch/contributionDispl ay.py?contribId=30&sessionId=6&confId=328 LOCATION:CERN Council Chamber\, 503/1-001 URL:http://indico.cern.ch/contributionDisplay.py?contribId=30&sessionId=6& confId=328 END:VEVENT BEGIN:VEVENT SUMMARY:Nuclear Moments of Isomeric States at REX-ISOLDE - Ideas and Neces sities DTSTART;VALUE=DATE-TIME:20060208T092500Z DTEND;VALUE=DATE-TIME:20060208T094500Z DTSTAMP;VALUE=DATE-TIME:20130523T122437Z UID:indico-contribution-328-51@cern.ch DESCRIPTION:Speakers: Dr. GEORGIEV\, Georgi (IPNO)\nThe nuclear moments ar e an important ingredient of our nuclear structure\nknowledge.

For the calculations\nof the various pathways fro m hydrogen to the heavier elements the nuclear properties\nof a large numb er of nuclides need to be known [1\,2]. Especially in the case of the\nr-p rocess\, where elements heavier than iron are formed by rapid neutron capt ure\,\nnuclear structure data of neutron-rich nuclides far from the valley of stability are\nrequired.\n\nThe path of the r-process is determined by and reflects nuclear structure. For\nexample at the neutron shell N=50 it crosses through the waiting point nuclide 80Zn.\nSlight deviations in the nuclear physics parameters can lead to large discrepancies\nin the modeli ng of the subsequent nucleosynthesis processes. One crucial parameter is\n the mass of the nuclides\, which enters the determination of neutron separ ation\nenergies and the Q-values for the beta decays. They are thus essent ial for the study\nof the r-process.\n\nWith the Penning trap mass spectro meter ISOLTRAP at ISOLDE/CERN very precise and\naccurate mass measurements with relative mass uncertainties down to dm/m=8x10-9 can\nbe achieved. Re cently\, the atomic masses of the neutron-rich zinc isotopes 71-81Zn\nhave been measured. For the first time the masses of 79Zn and 81Zn have been\n determined.
