  In the present work, we have reported a comprehensive shell-model study of
GT-strengths for recently available experimental data for $^{60}$Ga and
$^{62}$Ga from RIKEN Nishina Center [Phys. Rev. C 103, 014324 (2021)] populated
by $\beta $ 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 $fp$ 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 $fp$ model space are in a
reasonable agreement with the available experimental data.
