We report on a shell-model study of nuclei with four valence nucleons in the (132)Sn and (208)Pb regions. This aims at investigating to what extent the striking similarity existing between the low-energy properties of (134)Sb and (210)Bi persists when adding a pair of identical particles. We employ realistic low-momentum effective interactions derived from the CD-Bonn nucleon-nucleon potential through use of the V(low-k) approach. The calculated results are in very good agreement with the available experimental data and emphasize the persistence of a close resemblance between the spectroscopy of the two regions when moving away from the one proton-one neutron systems.

Abstract
We report on a shell-model study of nuclei with four valence nucleons in the (132)Sn and (208)Pb regions. This aims at investigating to what extent the striking similarity existing between the low-energy properties of (134)Sb and (210)Bi persists when adding a pair of identical particles. We employ realistic low-momentum effective interactions derived from the CD-Bonn nucleon-nucleon potential through use of the V(low-k) approach. The calculated results are in very good agreement with the available experimental data and emphasize the persistence of a close resemblance between the spectroscopy of the two regions when moving away from the one proton-one neutron systems.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
