摘要

本研究利用壳模型研究了 sd 壳区的伽莫-泰勒转变强度分布。利用sd-shell中的USDB和USDA有效相互作用，使用壳模型对34Ar→34Cl、34S→34Cl、37Cl→37Ar和37Ca→37K等原子核的B(GT)及其累积和∑B(GT)进行了计算。对原子核的跃迁进行了研究。讨论了 B(GT)和 ∑B(GT)的结果，并与最新的观测数据进行了比较。测得的 GT 分布和累积跃迁强度 B(GT) 与理论计算结果相当吻合。我们确定了单个转变的定性一致，测量的累积转变强度几乎与观测到的一致。

INVESTIGATION OF GAMOW-TELLER STRENGTHS FOR A=34 AND A=37 NUCLEI

In this work, the Gamow-Teller transition strength distributions in sd-shell region were investigated by using shell model. The calculations of B(GT) and their accumulated sum ∑B(GT) for the nuclei 34Ar→34Cl, 34S→34Cl, 37Cl→37Ar, and 37Ca→37K were performed using the shell model by utilizing the USDB and USDA effective interactions in the sd-shell. The transitions for the nuclei are studied. The results for the B(GT) and ∑B(GT) are discussed and compared to the most recent observed data. The measured GT distributions and the cumulative transition intensities B(GT) are in a fair amount of agreement with the theoretical calculations. We have established a qualitative agreement for the individual transformations, and the measured cumulative transformation strengths nearly match the observed ones.
