Shell model results for nuclear $\beta^-$-decay properties of $sd$ shell nuclei

Nuclear Theory 2020-03-23 v4 Nuclear Experiment

Abstract

We evaluate the allowed β\beta^--decay properties of nuclei with Z=815Z = 8 - 15 systematically under the framework of the nuclear shell model with the use of the valence space Hamiltonians derived from modern ab intioab~intio methods, such as in-medium similarity renormalization group and coupled-cluster theory. For comparison we also show results obtained with fitted interaction derived from the chiral effective field theory and phenomenological USDB interaction. We have performed calculations for O \rightarrow F, F \rightarrow Ne, Ne \rightarrow Na, Na \rightarrow Mg, Mg \rightarrow Al, Al \rightarrow Si, Si \rightarrow P and P \rightarrow S transitions. Theoretical results of B(GT)B(GT), logftft values and half-lives, are discussed and compared with the available experimental data.
