摘要

针对核图中 Pb208 南区的富中子核进行了大规模壳模型计算。利用 Pb208 区域最近的有效相互作用,计算了这些富中子原子核的 β 衰变特性,如 logft、平均形状因子值、半衰期和部分衰变率。这些计算是在核N≤126的特定模型空间中进行的,没有截断;此外,在破核核(Z≤82,N>126)的情况下,还包括了粒子洞激发。与实验数据进行了广泛的比较,并提出了几种状态的自旋奇偶性。

Shell-model study for allowed and forbidden β− decay properties in the mass region “south” of Pb208
The large-scale shell-model calculations have been performed for the neutron-rich nuclei in the south region of Pb208 in the nuclear chart. The β-decay properties, such as the logft, average shape factor values, half-lives, and partial decay rates are calculated for these neutron-rich nuclei using recent effective interaction for the Pb208 region. These calculations have been performed without truncation in a particular model space for nuclei N126; additionally, particle-hole excitations are included in the case of core-breaking nuclei (Z82,N>126). An extensive comparison with the experimental data has been made, and spin parities of several states have been proposed.
