Abstract

Excited states in 96Ag were populated in fragmentation of an 850-MeV/u 124Xe beam on a 4-g/cm2 Be target. Three new high-spin isomers were identified and the structure of the populated states was investigated. The level scheme of 96Ag was established, and a spin parity of (13−), (15+), and (19+) was assigned to the new isomeric states. Shell-model calculations were performed in various model spaces, including πν(p1/2,g9/2,f5/2,p3/2) and the large-scale shell-model space πν(gds), to account for the observed parity changing M2 and E3 transitions from the (13−) isomer and the E2 and E4 transitions from the (19+) core-excited isomer, respectively. The calculated level schemes and reduced transition strengths are found to be in very good agreement with the experiment.

N2 - Excited states in 96Ag were populated in fragmentation of an 850-MeV/u 124Xe beam on a 4-g/cm2 Be target. Three new high-spin isomers were identified and the structure of the populated states was investigated. The level scheme of 96Ag was established, and a spin parity of (13−), (15+), and (19+) was assigned to the new isomeric states. Shell-model calculations were performed in various model spaces, including πν(p1/2,g9/2,f5/2,p3/2) and the large-scale shell-model space πν(gds), to account for the observed parity changing M2 and E3 transitions from the (13−) isomer and the E2 and E4 transitions from the (19+) core-excited isomer, respectively. The calculated level schemes and reduced transition strengths are found to be in very good agreement with the experiment.
