Transition strengths and band terminations in Zr-86
(2003) In Physical Review C: covering nuclear physics 67. p.1-034320- Abstract
- High angular momentum states in Zr-86 were populated through the Ni-58(S-32,4p) reaction at 135 MeV using the 88-In. Cyclotron at Lawrence Berkeley National Laboratory. Recoiling Zr-86 nuclei were stopped in a thick Ta backing. Prompt multi-gamma coincidences with evaporated charged particles were detected using the full array of GAMMASPHERE and the MICROBALL. Mean lifetimes of 36 levels in Zr-86 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... (More)

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. (Less)
