论文摘要
在目前的工作中，我们报告了一项全面的外壳模型研究，对$^{208} $ pb的东北地区禁止$β^ - $β^ - $β^ - $β^ - $β^ - $β^ - $β^ - $β^ - $^{208} $ pb的全面研究。为此，我们考虑了$^{210-215} $ pb $ \ rightarrow $ $^{210-215} $ bi和$^{210-215} $^$ $ $ \ rightarrow $ $ $ $^{210-215} $ po po transitions。我们已经使用KHPE相互作用在Valence Shell 82-126中对质子进行了壳模型计算，而中子的中子为126-184进行了计算，而没有任何截断。我们还为相关核计算了半衰期和Q值。最近，观察到几个$ \ log ft $ vuale，与$β^ - $衰减相对应的（8 $^ - $）$^{214} $^{214} $ bi $^m $在Cern-Isolde设施[Phys。 Rev. C {\ BF 104}，054301（2021）]，这是我们首次报道了这些过渡的壳模型结果。
In the present work, we report a comprehensive shell-model study of the $\log ft$ values for the forbidden $β^-$ decay transitions in the north-east region of $^{208}$Pb. For this we have considered $^{210-215}$Pb $\rightarrow$ $^{210-215}$Bi and $^{210-215}$Bi $\rightarrow$ $^{210-215}$Po transitions. We have performed shell-model calculation using KHPE interaction in valence shell 82-126 for protons and 126-184 for neutrons without any truncation. We have also calculated half-lives and Q-values for the concerned nuclei. Recently several $\log ft$ values are observed corresponding to $β^-$ decay from (8$^-$) isomeric state of $^{214}$Bi$^m$ at CERN-ISOLDE facility [Phys. Rev. C {\bf 104}, 054301 (2021)], and for the first time we have reported shell-model results for these transitions.
