论文摘要
在目前的工作中，我们报告了使用显微镜有效的价值壳相互作用（即N3Lo，JISP16和DJ16A），对$ sd $ shell nuclei si和p的中子数量从$ n = 9 $到$ n = 20 $不等。这些有效的$ SD $ -SHELL交互是使用\ textit {ab intio}开发的，}无核壳模型波函数和Okubo-Lee-Suzuki转换方法。为了进行比较，我们还使用了经验USDB相互作用进行了壳模型计算。已经研究了这些同位素链的能光谱和电磁特性。理论上计算的壳模型结果与可用的实验数据进行了比较，以检查这些微观相互作用的预测强度。发现与其他显微镜相互作用相比，与DJ16A相互作用更好地再现了基态的结合能，并且在Si中获得了$ z = 14 $的质子子壳闭合。提出了两体相互作用的自旋张量分解，以了解中央，矢量和张量成分对这些相互作用的贡献。 $^{23} $ al（$ d $，$ n $）$^{24} $ si的光谱强度在NSCL进行了检查。
In the present work, we have reported comprehensive study of the $sd$-shell nuclei Si and P with neutron number varying from $N = 9$ to $N = 20$ using the microscopic effective valence shell interactions, namely, N3LO, JISP16 and DJ16A. These effective $sd$-shell interactions are developed using the \textit{ab initio} no-core shell model wave functions and the Okubo-Lee-Suzuki transformation method. For comparison, we have also performed shell model calculations with the empirical USDB interaction. Energy spectra and electromagnetic properties of these isotopic chains have been studied. Theoretically calculated shell model results are compared with the available experimental data, to check the predictive strength of these microscopic interactions. It is found that the binding energies of the ground states are better reproduced with the DJ16A interaction as compared to other microscopic interactions and a proton subshell closure at $Z=14$ is obtained in Si. Spin-tensor decomposition of two-body interaction is presented to understand the contributions from central, vector and tensor components into these interactions. Spectroscopic strengths of $^{23}$Al($d$,$n$)$^{24}$Si are examined for the newly performed experiment at NSCL.
