Abstract

High angular momentum states in odd-odd [Formula Presented] were populated through the [Formula Presented] reaction at 135 MeV. Recoiling [Formula Presented] nuclei were stopped in a thick Ta backing. Prompt multi-[Formula Presented] coincidences with evaporated charged particles were detected using the full array of Gammasphere and the Microball. Mean lifetimes of 51 levels in [Formula Presented] were measured using the Doppler-shift attenuation method. Strongly alternating magnetic dipole transition strengths were observed in the yrast positive-parity bands. Most of the transition quadrupole moments inferred from the lifetimes lie in the range of 1 to [Formula Presented] which would correspond to quadrupole deformations [Formula Presented] of 0.10 to 0.27 in a rotational model. Comparison with Hartree-Fock-Bogoliubov cranking calculations suggests triaxial to oblate shapes.
