摘要

利用三轴投影壳模型（TPSM）方法对奇数质量$^{117-127}$I 核的高自旋能带结构进行了全面分析。利用相关参数的合适值，奇数质量（^{117-127}\）I 的估计能谱与实验结果非常吻合。势能面显示同位素正从（\γ \）软性走向刚性。目前的分析进一步揭示了沿着 yrast 和 yrare 线的典型带交叉是由三准粒子带与一准粒子带交叉造成的。此外，还计算了过渡概率[B(E2) 和 B(M1)]，发现它们与现有的实验数据一致。还讨论了 $^{123}$ I 中的手性。

Microscopic study of near yrast band structures in odd-mass $^{117-127}$I isotopes

A comprehensive analysis of high spin band structures for odd mass $^{117-127}$I nuclei is performed using Triaxial Projected Shell Model (TPSM) approach. Using suitable values for the relevant parameters, the estimated energy spectrum of odd mass $^{117-127}$I agrees well with the experimental results The potential energy surfaces reveal that the isotopes are heading from $\gamma $-softness towards rigidity. The current analysis further revealed that the typical band crossing along the yrast as well as the yrare line is caused by the three-quasipaticle band crossing the one-quasiparticle band. Further, transitional probabilities [B(E2) and B(M1)] have been computed and found to be consistent with the available experimental data. Chirality in $^{123}$ I has also been discussed.
