Abstract
Lifetime measurements have been performed using the () reaction at a beam energy of 380 MeV, and the recoil distance Doppler-shift method. In a second experiment the () reaction at a beam energy of 88 MeV using the Ge-gated fast timing technique was used to determine lifetimes. Lifetimes of the four lowest yrast states of have been determined. The experimental data are compared to calculations within the framework of the interacting boson model and the general collective model. Both models predict a deformed ground state and are consistent with all the remaining experimental results.
