Shell model results for nuclear β--decay properties of sd-shell nuclei

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