DSA lifetime measurements and structure of positive-parity bands of 120Xe
- 113 Downloads
Lifetimes of excited states in 120Xe have been measured by the Doppler-shift attenuation method in the 111Cd( 12C,3n) reaction at a beam energy of E = 56 MeV. Lifetime values for 22 states were obtained. The excitation energies and E2-transition probabilities of the yrast band, γ-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.
