Abstract

Lifetimes of states within a triaxial band belonging to the $γ$ -soft nucleus $^{133} Ce$ have been determined through a Doppler-broadened line shape analysis. A value, $Q_{t} \approx 2.2$ $e b,$ has been found for the transition quadrupole moment which is considerably smaller than that of superdeformed structures ${(Q}_{t} \approx 7.4$ $e b)$ in this mass region. The results are discussed in terms of deformation self-consistent calculations based on the total Routhian surface formalism.
