46. Study of Gamow Teller transitions using beta decay and charge exchange reactions

Prof. Berta Rubio (IFIC)

Invited

The study of the properties of nuclei far from stability is one of the main frontiers of modern nuclear physics. Among many possible observables for nuclear structure, the $\beta$ decay strengths provide important testing grounds for nuclear structure theories far from stability. The mechanism of $\beta$ decay is well understood and dominated by allowed Fermi (F) and Gamow-Teller (GT)...

45. Hyperfine structure studies of At isotopes using in-source laser spectroscopy at ISOLDE

J. G. Cubiss* University of York (UK) The competition between spherical and deformed configurations at low energy gives rise to shape coexistence in the neutron-deficient isotopes around the Z=82 shell closure [1], while on the neutron-rich side effects due to octupole deformation could be important. In order to determine the extent to which the ground and isomeric states of these...

61. Study of multi-neutron emission in the beta-decay of 11Li

Dr Franck Delaunay (LPC Caen, France)

Submitted

Beta-decay spectroscopy is one of the most important tools for the study of nuclear structure. In exotic nuclei beta-decay can often be followed by the emission of delayed particles, a process which becomes the dominant decay channel when approaching the driplines. In the most exotic species, the emission of two or more delayed particles can also occur with a significant...

14. Study of the $^{129}$Sn structure by beta decay: On the nature of the $3/2^+$ ground state and $1/2^+$ $315.3$-keV level

Razvan Lica (IFIN-HH Bucharest (RO))

Submitted

We have investigated levels in $^{129}$Sn populated from the $\beta^-$ decay of $^{129}$In isomers at the ISOLDE facility. The $^{129}$Sn nucleus is a three-neutron hole system next to the doubly magic $^{132}$Sn. The involved states of spin $1/2^+$ and $3/2^+$ are expected to have a configuration determined by the neutron $s_{1/2}$ and $d_{3/2}$ single particle states, respectively....

37. Estimation of production rates and secondary beam intensities

Martin Veselsky (Slovak Academy of Sciences (SK))

16/12/2014, 14:25

Submitted

Summary of the work, performed as a part of the project Eurisol Design Study, will be presented and possibilities for further activities at the HIE-ISOLDE will be discussed. As a part of the Eurisol Design Study, dedicated task Beam Intensity Calculation focused on possibilities to predict achievable secondary beam intensities at the ISOL facility using the spallation reaction. Model...
