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

Abstract

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.
