论文摘要
已经进行了大规模的壳模型计算，以研究132SN及其最近的邻居的激发光谱，其新的交叉壳相互作用是由该质量区域的两个广泛使用的相互作用SN100PN和CWG构建的。已经调整了一些两体矩阵元素，以重现132SN的低洼多重状态。这是132SN能源光谱以及过渡概率的首次全尺度壳模型研究。其他最近邻居的激发光谱很好地复制了。最重要的可观察到的是E1过渡概率，它们远远超出了与现有相互作用的计算范围。
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. This is the first full scale shell model study of 132Sn energy spectra as well as transition probabilities. The excitation spectra for other nearest neighbours are reproduced reasonably well. The most important observable calculated are the E1 transition probabilities, which were so far beyond the scope of calculations with the existing interactions.
