112. Shape coexistence at the neutron rich edge; The cases of N=20, 28 and 40.

Dr Alfredo Poves (Institute the Theoretical Physycs, Madrid, Spain)

5/21/12, 11:30 AM

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

109. Study of nuclei north-east of 48Ca with realistic effective hamiltonians

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...

82. Shell evolution and effective three-body forces in the newly-explored neutron-rich region around Z=82 and far beyond N=126

Mr Andrea Gottardo (INFN - LNL)

5/21/12, 12:20 PM

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....

49. Study of quadrupole collectivity in neutron-rich 128Cd

Prof. Thorsten Kröll (TU Darmstadt)

5/21/12, 12:40 PM

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...
