Systematic study of the nature of gamma bands in A = 100–200 mass nuclei

Abstract

The [Formula: see text]-bands are analyzed through the variation of the energy of the [Formula: see text] excitation and the energies of excited level sequence of [Formula: see text]-bands with respect to various parameters. The shape phase transition observed at N = 88–90 is reviewed through its influence on the energies of [Formula: see text]-band. The correlation of the [Formula: see text] excitation energies with the collective shape signature observable [Formula: see text] indicates a connection with the nuclear equilibrium structure. The study of excited level sequence in the [Formula: see text]-band with respect to the ground band signifies that the two bands differ in deformation.
