Study of $β^- $ decays for sd model space with Shell model

Surender Siwach

AI总结:

本研究利用USDB相互作用通过壳模型计算分析了sd模型空间内原子核的β衰变特性,并与Z=8-19的核实验数据对比,为相关核衰变性质和壳层结构研究提供参考。

摘要:

本文研究了sd模型空间内原子核的β衰变,该模型空间包含$0d_{3/2}$、$0d_{5/2}$和$1s_{1/2}$壳层。我们全面分析了其衰变特性,包括半衰期、$logft$值、Q值、分支比、B(GT)值、M(GT)和R(GT)值。我们采用原子核壳模型框架,将这些结果与Z=8-19的原子核实验数据进行对比。计算使用USDB\footnote{usdb}相互作用完成,该相互作用非常适用于价核子处于$0d_{3/2}$、$0d_{5/2}$和$1s_{1/2}$壳层的原子核。本研究为理解这些原子核的β衰变性质提供了宝贵见解,也有助于深化我们对核壳层结构的认识。

英文摘要:

This paper investigates the beta decay of nuclei within the sd model space, encompassing the $0d_{3/2}$, $0d_{5/2}$, and $1s_{1/2}$ shells. We comprehensively analyze their decay characteristics, including the half-life, $logft$ value, Q value, branching ratio, B(GT) value, M(GT), and R(GT) value. These results are compared with experimental data from Z = 8-19 nuclei, employing the nuclear shell model framework. The calculations are performed using the USDB\cite{usdb} interaction, which is well-suited for nuclei with active valence nucleons in the $0d_{3/2}$, $0d_{5/2}$, and $1s_{1/2}$ shells. The study offers valuable insights into the beta decay properties of these nuclei and contributes to our understanding of the nuclear shell structure.}
