Gamow-Teller strengths of some sd-shell nuclei in the shell model framework

S. M. Obaid, H. M. Tawfeek


The nuclear Gamow-Teller (GT) transition strength distributions B(GT)
have been studied for some sd-shell nuclei in the (3He, t) charge-exchange
reactions. The shell model calculations were performed by employing the
USDA and USDB effective interactions in the sd-model space. The re
sults of B(GT) calculations reproduce the the experimental Gamow-Teller
strength distributions well, while the calculated distribution of summed
GT transition strengths were closely reproduce the observed ones.
