摘要:

本文提出了Z $\geq$ 90的$β$稳定区.计算的$β$稳定区的$β$稳定核与Möller \emph{et al}的结果符合得很好.计算了靠近$β$稳定区的核的半衰期,系统地研究了$α$ -衰变和$β$ -衰变之间的竞争.计算的半衰期和建议的衰减模式是很好地符合实验结果。给出了Z = 107 $-$ 110核的半衰期和衰变模式的预测。

英文摘要:

In this work, the $β$-stable region for Z $\geq$ 90 is proposed. The calculated $β$-stable nuclei in the $β$-stable region are in good agreement with the ones obtained by Möller \emph{et al}.. The half-lives of the nuclei close to the $β$-stable region are calculated and the competition between $α$-decay and $β$-decay is systematically investigated. The calculated half-lives and the suggested decay modes are well in line with the experimental results. The predictions for half-lives and decay modes of the nuclei with Z = 107$-$110 are presented.
