Abstract
Lifetimes of excited states in Xe-120 have been measured by the Doppler-shi ft attenuation method in the Cd-111(C-12,3n) reaction at a beam energy of E = 56 MeV. Lifetime values for 22 states were obtained. The excitation ener gies and EB-transition probabilities of the yrast band, gamma -band and its continuation are interpreted in the framework of a version of IBFM (IBM 2 q.p.). A reasonable description of the B(E2) behavior in the backbending region is achieved.
