Abstract We evaluate the allowed β--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), log ft values, and half-lives are discussed and compared with the available experimental data.
