Lifetime measurements in {sup 133}Ce
- Laboratorio Pelletron, Departamento de Fisica Nuclear, Instituto de Fisica, Universidade de Sao Paulo, Sao Paulo (Brazil)
Lifetimes of low-lying levels in the one- and three-quasiparticle bands in {sup 133}Ce have been measured using the recoil-distance Doppler-shift technique. The E2 transition strengths extracted for the negative parity yrast states are well described by the triaxial-rotor-plus-quasiparticle and the geometrical models, but the interacting-boson-plus-fermion predictions are too small by about a factor of 3. The B(M1) values extracted for the levels in the positive parity three-quasiparticle band are consistent with the previous {nu}h{sub 11/2}{circle_times}{pi}h{sub 11/2}{circle_times}{pi}g{sub 7/2} configuration assignment to this band. {copyright} {ital 1997} {ital The American Physical Society}
