Abstract
second-forbidden nonunique β− decays of 24Na(4+) →24Mg(2+) and 36Cl(2+) →36Ar(0+) transitions under
the framework of the nuclear shell model. We have performed the shell model calculations in the sd model
space, using more recent microscopic effective interactions such as Daejeon16, chiral N3LO, and JISP16. These
interactions are derived from the no-core shell model wave functions using Okubo-Lee-Suzuki transformation.
For comparison, we have also shown the results obtain from the phenomenological USDB interaction. To test the
predictive power of these interactions first we have computed low-lying energy spectra of parent and daughter
nuclei involved in these transitions. The computed results for energy spectra, nuclear matrix elements, log f t
values, shape factors, electron spectra, and decomposition of the integrated shape factor are reported and compare
with the available experimental data.
