Title: Medium-spin {gamma}-ray spectroscopy of the transitional nucleus {sup 160}Er

Abstract

The nucleus {sup 160}Er, with the structural parameter R{sub 4/2}=E(4{sub 1}{sup +})/E(2{sub 1}{sup +})=3.10, falls on the transition path between the critical point of the vibrator-rotor shape phase transition and the rigid rotor limit, thus serving as a critical test of the CBS rotor model, which describes this transition region. Medium-spin states of {sup 160}Er have been populated via the reaction {sup 159}Tb({sup 6}Li,5n) and new levels have been identified and interpreted as the even-spin members of the {gamma} band and members of the {beta} vibrational band. Level energies and branching ratios are compared to the CBS rotor model predictions.
