Abstract

Two experiments have been performed using the [Formula Presented] reaction at 135 MeV with Gammasphere and the Microball to study the high-spin structure of the transitional nucleus [Formula Presented] The first experiment using a thin target provided a considerable extension and refinement of the level scheme, as well as firm spin assignments from directional correlation of oriented nuclei. Sub-picosecond lifetimes were measured in the second backed-target experiment using the Doppler-shift attenuation method. The lifetimes imply a rather modest average deformation of [Formula Presented] but with considerable variation from state to state. Strong alternations were observed in the [Formula Presented] strengths of transitions between some pairs of bands. The experimental results were compared with calculations performed within the cranked Nilsson-Strutinsky approach. The calculations generally reproduce the irregularities in the structure of the yrast lines and plunging transition quadrupole moments [Formula Presented] within the bands explaining them as reflections of configuration changes and an approach of band termination, respectively.
