Abstract
Lifetimes of low-lying levels in the one and three-quasiparticle bands in Ce-133 have been measured using the recoil-distance Doppler-shift technique. The E2 transition strengths extracted for the negative pari ty yrast states are well described by the triaxial-rotor-plus-quasipar ticle and the geometrical models, but the interacting-boson-plus-fermi on predictions are too small by about a factor of 3. The B(M1) values extracted for the levels in the positive parity three-quasiparticle ba nd are consistent with the previous vh(11/2)x pi h(11/2)x pi g(7/2) co nfiguration assignment to this band.
