Recent studies have provided new experimental information on the very neutron-rich nucleus 135Sb. We have performed a shell-model calculation for this nucleus by using a realistic effective interaction derived from the CD-Bonn nucleon-nucleon potential. This gives a very good description of the observed properties of 135Sb. We show that the anomalously low position of the first excited state, Jπ=5/2+, and the strongly hindered M1 transition to the ground state have their origin in the effective neutron-proton interaction.

Abstract
Recent studies have provided new experimental information on the very neutron-rich nucleus 135Sb. We have performed a shell-model calculation for this nucleus by using a realistic effective interaction derived from the CD-Bonn nucleon-nucleon potential. This gives a very good description of the observed properties of 135Sb. We show that the anomalously low position of the first excited state, Jπ=5/2+, and the strongly hindered M1 transition to the ground state have their origin in the effective neutron-proton interaction.| File | Dimensione | Formato | |
