Shell evolution in the neutron rich nuclei II
Considerable efforts have been recently deployed in order to reach experimentally the region in the immediate vicinity of 78Ni to assess the doubly magic character of this very neutron rich nucleus. The PARRNe ISOL device has been operating at IPN Orsay since more than a decade. Originally conceived as a test bench for R&D studies in the framework of the SPIRAL2 project, the performance of the...

Shell evolution in the neutron rich nuclei II
It has been shown that the neutron 2d5/2 orbital has to be included in shell-model calculations to explain the appearance of large quadrupole collectivity observed in the neutron rich Fe and Cr of the N ≈ 40 region. This work initiated by Caurier et al. has been recently revisited. Calculations in a large valence space involving the fp proton shell and the fpgd neutron shells including a...

Shell evolution in the neutron rich nuclei II
Over the past several years various shell-model studies have been
performed for neutron-rich nuclei beyond 132Sn, all leading to
spectroscopic properties in very good agreement with the experimental data (see for instance [1,2] and references therein). In these works, a unique Hamiltonian has been used with the single-particle energies taken from the experiment and the two-body effective...

Shell evolution in the neutron rich nuclei II
Electromagnetic transition rates, in particular for E2 transitions, are a sensitive and well-studied probe of nuclear structure: their dependence on the nuclear wave function offers the possibility of strict tests of theoretical models. Usually, B(E2) rates are calculated in a restricted shell-model space and they are then renormalized with constant effective charges. However, even large-scale...
