Abstract

Excited states in ${}^{127}{Xe}$ were populated via ${}^{122}{Sn} (^{9} Be, 4 n γ)$ fusion-evaporation reaction at $E_{beam} = 48$ MeV. A rotational band above an isomeric state at 2730.3 keV has been established. $J^{π} = 23 / 2^{+}$ has been assigned unambiguously to the bandhead. Structural features, configuration, and reduced hindrance factor per degree of $K$ -forbiddenness ( $f_{ν}$ ) have been discussed in the context of neighboring nuclei. Half-lives of $7 / 2^{+}$ ( $t_{1 / 2} = 37 \pm 1$ ns) and $23 / 2^{+}$ ( $t_{1 / 2} = 28 \pm 1$ 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 $β_{2} \sim 0.22$ and $15^{\circ} ≲ γ ≲ 22^{\circ}$ .
