The structure of tin isotopes with a global optimized effective interaction

Abstract

A systematic shell model calculation on the structure of light tin isotopes is presented with a monopole-optimized effective interaction. We started with the realistic CD-Bonn potential. The unknown single-particle energies and the T = 1 monopole interactions are determined by fitting to the binding energies of the yrast states of nuclei 102-132Sn. The mean deviation from experimental data is around 120 keV. In particular, we analyzed the origin of the spin inversion between 101Sn and 103Sn.
