In the present work, we have reported /EC-decay half-lives for 
–30 nuclei using large-scale shell-model. A recent study shows that some proton-rich nuclei in this region belong to the island of inversion. We have performed calculations for these nuclei using KB3G effective interaction, while for Ni, Cu, and Zn nuclei we have used JUN45 effective interaction in the 
model space. The calculated quenching factors for fp and space using KB3G and JUN45 effective interactions are also reported. Shell-model results of 
-decay half-lives, excitation energies, logft values, and branching fractions are discussed and compared with the available experimental data. We have obtained a reasonable agreement with the available data.
