Shell-model study for GT-strengths corresponding to $β$ decay of $^{60}$Ge and $^{62}$Ge

Abstract

In the present work, we have reported a comprehensive shell-model study of GTstrengths for recently available experimental data for 60 Ga and 62 Ga from RIKEN Nishina Center [Phys. Rev. C 103, 014324 (2021)] populated by β decay of the 60 Ge and 62 Ge, respectively. We have performed shell-model calculations in two different model spaces, the first set of calculations in the f p model space using KB3G and GXPF1A interactions, while the second set in f 5/2 pg 9/2 model space using JUN45 and jj44b effective interactions. Our shell-model results in f p model space are in a reasonable agreement with the available experimental data.
