摘要

用束内γ射线能谱法研究了主要与低j νs1/2和νd3/2准粒子构型有关的低洼单准中子带。激发态是通过能量为15 MeV的2H光束轰击元素127I目标而填充的。这项研究证实了先前确定的、人口稀少的不受欢迎的νd3/2波段的特征伙伴，并为该波段内的两个低洼状态提供了确定的自旋和宇称分配。利用三轴投影壳模型进行的理论计算较好地再现了实验观测结果。

Low-j rotational bands in 127Xe

Low-lying one-quasineutron bands, primarily associated with the low-j

ν s_{1 / 2}

and

ν d_{3 / 2}

quasiparticle configurations, have been investigated by means of in-beam

γ

-ray spectroscopy. Excited states were populated through the bombardment of a ²H beam with an energy of 15 MeV on an elemental ¹²⁷I target. This study confirms the previously identified, feebly populated unfavoured signature partner of the

ν d_{3 / 2}

band, and provides firm spin and parity assignments for two low-lying states within this band. Theoretical calculations using the Triaxial Projected Shell Model reproduce the experimental observations well.
