Abstract
Lifetimes of excited states in were extracted from recoil-gated -ray spectra and recoil-gated -coincidence matrices using the recoil distance Doppler-shift method. States were populated using the (,) fusion-evaporation reaction. Measured lifetimes allowed transition probabilities, transition quadrupole moments, quadrupole deformation parameters, and transition dipole moments to be deduced for the band formed by the odd-spin yrast states. The experimental results confirm the low degree of octupole collectivity in this mass region.
