Abstract
Gamow-Teller transitions in nuclei of the regions close to the doubly closed shells at A = 16, 40, 56, and 100 are analyzed in the shell-model approach by considering the configuration mixing, core polarization, and by using the experimental values of the one-particle spectroscopic factors. The observed data on the β-decay half-lives are well reproduced by using the |G A /G V | value equal to 1.1(1).
