| Abstract: | Excited states in Xe127 were populated via Sn122(9Be,4nγ) fusion-evaporation reaction at Ebeam=48 MeV. A rotational band above an isomeric state at 2730.3 keV has been established. Jπ=23/2+ has been assigned unambiguously to the bandhead. Structural features, configuration, and reduced hindrance factor per degree of K-forbiddenness (fν) have been discussed in the context of neighboring nuclei. Half-lives of 7/2+ (t1/2=37±1 ns) and 23/2+ (t1/2=28±1 ns) isomeric states have also been estimated and found to be consistent with the earlier reported values. The experimentally observed energy levels of the rotational band have been reproduced successfully by theoretical calculations carried out using the modified particle rotor model (MPRM) with β2∼0.22 and 15γ. © 2018 American Physical Society. |
