4. Study of the N=50 major shell effect towards 78Ni : contribution from beta-decay studies at IPN Orsay

The PARRNe ISOL device has been operating at IPN Orsay since 10 years. Originally conceived as a test bench for R&D studies in the framework of SPIRAL2, the performance of the setup has proven suitable to undertake a physics research program on the evolution of N=50 towards 78Ni by beta-decay studies. During the past decade, several experiments were realized using either the Tandem as a...

9. Decay Spectroscopy in the vicinity of 78Ni

Study of doubly-closed-shell and neighboring nuclei provides great opportunities for testing of nuclear models and expanding our knowledge of nucleosynthesis processes. Especially, the region around 78Ni (Z=28, N=50) has attracted great interests because of its extreme neutron-to-proton ratio in the region far from the valley of stability. Despite of a great deal of theoretical activity...

10. Spectroscopy of neutron-rich nuclei around 110Zr

Shape evolution around 110Zr attracts much attention because shape transition from prolate to oblate, spherical or more exotic tetrahedral shapes has been predicted by many authors. 110Zr is expected to be a spherical shape due to a possible subshell closure at N=70 [1]. Furthermore, the transition to an oblate shape may appear in more neutron-rich region [2]. We performed the experiment...

6. b-decay spectroscopy study of neutron rich nuclei around the N=82 shell closure including the r-process waiting points 128Pd

Giuseppe Lorusso (RIKEN)

The b-decay study of the region around the N=82 shell closure is critical for r-process models. The experiment that we intend to perform with the addition of the EURICA spectrometer aims to study the decay of the N=82 nuclei 128Pd and 129Ag that are expected to be waiting points for the the r-process in most r-process models, and therefore their study will dramatically improve the reliability...

30. Beta decay of the neutron-rich 132,134Cd isotopes and search for 6+ isomers in 136,138Sn

34. Probing neutron-rich isotopes around doubly closed-shell 132Sn and doubly mid-shell 170Dy by combined beta-gamma and isomer spectroscopy

Hiroshi Watanabe (RIKEN Nishina Center)

23/05/2011, 17:40

I will present possible decay spectroscopy experiments using the E(U)RICA array at RIBF, aiming at studying neutron-rich nuclei in the vicinity of the doubly magic nucleus 132Sn and the doubly mid-shell nucleus 170Dy
