Nuclear structure far from stability
Oral
I will discuss the mechanisms responsible for the shape transitions and coexistence in the very neutron rich regions around the magic neutron closures N=20, 28 and 40. I will show that the islands of inversion/deformation at N=20 and 28 merge in the Magnesium isotopes

Nuclear structure far from stability
Oral
Shell-model calculations for nuclei with valence nucleons outside 48Ca are presented, wherein a fully microscopic approach is adopted. Namely, the single-particle energies and the matrix elements of both the two-body interaction and the electromagnetic multipole operators are derived theoretically starting from the high-precision CD-Bonn nucleon-nucleon potential, renormalized by way of the...

Nuclear structure far from stability
Oral
The study of exotic nuclei has shown that significant changes of the well known shell structure along the stability valley occur. However, little is known on the neutron-rich nuclei around 208Pb, because of the experimental difficulties to reach such nuclei. The study of these heavy nuclei is relevant also for the understanding of the r-process stellar nucleosynthesis in heavy nuclei....

Nuclear structure far from stability
Oral
The neutron-rich isotope 128Cd is only two proton and two neutron
holes away from the doubly-magic nucleus 132Sn. It is famous for the
irregular behaviour of the excitation energy of the first 2+ state,
a feature which cannot be explained even by recent shell model
calculations. Currently, only a beyond-mean-field approach is capable
to reproduce the anomaly. However, it predicts a...
