标题： Shell-model study of $\log ft$ values for $^{139,140,141}$Ba $\rightarrow$ $^{139,140,141}$La transitions

摘要： 在本工作中，使用大规模壳模型计算系统地研究了与钡同位素对应的β衰变性质，如$\log ft$值和半衰期。 对与$^{141}$Ba$\rightarrow$ $^{141}$ La对应的β衰变结果进行了广泛比较，该比较基于最近可用的实验数据。 此外，我们还计算了对应于$^{139}$Ba$\rightarrow$ $^{139}$ La 和$^{140}$Ba$\rightarrow$$^{140}$La 转变的核性质和β衰变性质。 此处考虑的模型空间是$Z=50-82$和$N=82-126$，其中包含$^{132}$Sn 核芯，这里采用的相互作用是 jj56pnb 相互作用。 使用壳模型计算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。 这是对最近实验数据的首次理论解释。 显示英文摘要

摘要： In the present work, beta-decay properties such as $\log ft$ 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 $^{141}$Ba$\rightarrow$ $^{141}$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 $^{139}$Ba$\rightarrow$ $^{139}$La and $^{140}$Ba$\rightarrow$ $^{140}$La transitions. The model-space considered here is $Z=50-82$ and $N=82-126$ with $^{132}$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.
