Abstract: | High-spin states in175Ta have been populated in the160Gd (19F,4n)175Ta reaction with beams provided by the HI-13 tandem accelerator at the Institute of Atomic Energy in Beijing. A level scheme was constructed from γ-γ coincidence experiments. Seven decay sequences built on 5/2+[402], 1/2?[541], 7/2+[404] and 9/2? [514] proton Nilsson configuration have been extended to higher spin. An anomalously large delay of the neutron AB crossing built on the h9/2 proton Nilsson State 1/2?[541] is discussed. |
