Large scale shell model study of the evolution of mixed-symmetry states in chains of nuclei around Sn-132

Abstract

Large scale shell model calculations based on a new diagonalization algorithm are performed in order to investigate the mixed symmetry states in chains of nuclei in the proximity of N=82. The resulting spectra and transitions are in agreement with the experiments and consistent with the scheme provided by the interacting boson model.
