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.
