Here we present the theoretical results for the Gamow-Teller two-neutrino double-beta decay (DBD) matrix elements for 0[sub 1][sup +][r arrow]0[sub 1][sup +] and 2[sub 1][sup +] transitions in the case of [sup 76]Ge to [sup 76]Se and [sup 82]Se to [sup 82]Kr nuclei. The calculations have been done in the framework of the variation after projection on the Hartree-Fock-Bogoliubov model with 2[ital p][sub 1/2], 2[ital p][sub 3/2], 1[ital f][sub 5/2], and 1[ital g][sub 9/2] valence space employing the modified Kuo-Brown interactions. The value of DBD half-lives result in excellent agreement for ground state (g.s.) to g.s. excitations of [sup 76]Ge and [sup 82]Se nuclei. Our results are in contrast with existing theoretical calculations for g.s. to 2[sup +] excited state and are much closer to the experimental limits.
