In the present work, beta-decay properties such as 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 Ba → La 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 Ba → La and Ba → La transitions. The model-space considered here is and with Sn 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 log⁡ft 值的壳模型研究

在目前的工作中，使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，例如值和半衰期。使用壳模型计算对应于 Ba → La 的 β 衰变结果与最近可用的实验数据进行了广泛的比较。此外，我们还计算了Ba→La和Ba→La跃迁对应的核和β衰变性质。这里考虑的模型空间是 和 具有 Sn 核心，这里采用的交互是 jj56pnb 交互。使用所有提到的同位素的壳模型计算得到的β衰变结果与可用的实验数据进行了比较。这是与最近的实验数据相对应的第一个理论解释。
