STRUCTURE OF ODD 79,81,83Se ISOTOPES WITH PROTON AND NEUTRON EXCITATIONS ACROSS Z = 28 AND N = 40

Abstract

The recently measured experimental data of 79,81,83 Se isotopes have been interpreted in terms of shell model (SM) calculations. The calculations have been performed in f5/2pg9/2 space with the recently derived interactions, namely JUN45 and jj44b. To study the importance of the proton excitations across the Z = 28 shell in this region, we have also performed calculation in fpg9/2 valence space using an fpg effective interaction with 48 Ca core and imposing a truncation. Excitation energies, B(2) values, quadrupole moments and magnetic moments are compared with the experimental data available. Present study reveals the importance of proton excitations across the Z = 28 shell for predicting quadrupole and magnetic moments.
