Abstract

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\citeusdb 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.
