Large-scale shell-model calculations have been performed to study the excitation spectra of 132Sn and its nearest neighbours with a new cross-shell interaction constructed from two widely used interactions, sn100pn and CWG, of this mass region. A few of the two-body matrix elements have been tuned to reproduce the low-lying multiplet states of 132Sn. The energy spectra and the transition probabilities of 132Sn have been calculated within an extended space. The results reproduce even the most recent data. The excitation spectra for other nearest neighbours and the transition probabilities related to core-excited states are reproduced reasonably well. However, calculated E1 transition probabilities are under-predicted in most cases.

双幻132 Sn 及其最近邻中的跨壳激发

已经进行了大规模壳模型计算,以研究132 Sn 及其最近邻的激发光谱,并使用由两种广泛使用的相互作用构建的新跨壳相互作用,n100nCWG,属于这个大众区域。一些二体矩阵元素已经过调整,以重现132 Sn的低位多重态。已在扩展空间内计算了132 Sn 的能谱和跃迁概率。结果甚至重现了最新的数据。其他最近邻的激发光谱和与核心激发态相关的跃迁概率得到了相当好的再现。然而,在大多数情况下,计算出的 E1 转移概率都被低估了。
