Abstract

High angular momentum states in ⁸⁶Zr were populated through the ⁵⁸Ni(³²S,4p) reaction at 135 MeV using the 88-In. Cyclotron at Lawrence Berkeley National Laboratory. Recoiling ⁸⁶Zr nuclei were stopped in a thick Ta backing. Prompt multi-γ coincidences with evaporated charged particles were detected using the full array of GAMMASPHERE and the MICROBALL. Mean lifetimes of 36 levels in ⁸⁶Zr were measured using the Doppler-shift attenuation method. Transition quadrupole moments Q_t were found in the range of about 0.3-1.5 e b in the positive-parity bands. The negative-parity bands show Q_t values from about 0.25 to 1.2 e b. In the yrast positive-parity band, a sharp drop in collectivity approaching the 30⁺ state supports the interpretation of band termination in this configuration. Decreasing Q_t values approaching the 24⁺ and 27^- states also provide an indication of terminating structures.
