Abstract

In the present work, beta-decay properties such as logft values and half-lives have been systematically studied corresponding to Ba isotopes using large-scale shell-model calculations. An extensive comparison of beta decay results corresponding to 141Ba → 141La using shell-model calculations is made with the recently available experimental data. In addition, we have also calculated the nuclear and beta decay properties corresponding to 139Ba → 139La and 140Ba → 140La transitions. The model-space considered here is Z=5082 and N=82126 with 132Sn core, and the interaction employed here is jj56pnb interaction. The beta decay results using shell-model calculations for all the mentioned isotopes are compared with the available experimental data. This is the first theoretical interpretation corresponding to recent experimental data.

139,140,141Ba→139,140,141La跃迁对数值的壳模型研究
在本研究中,利用大规模壳模型计算系统地研究了与 Ba 同位素相对应的β衰变特性,如 logft 值和半衰期。利用壳模型计算对 141Ba → 141La 的β衰变结果与最近获得的实验数据进行了广泛的比较。此外,我们还计算了与 139Ba → 139La 和 140Ba → 140La 转变相应的核和β衰变特性。这里考虑的模型空间是以 132Sn 为核的 Z=50-82 和 N=82-126,采用的相互作用是 jj56pnb 作用。利用壳模型计算得出的所有上述同位素的β衰变结果与现有的实验数据进行了比较。这是首次与最新实验数据相对应的理论解释。
