Half-lives T{sub 1/2}{sup 2{nu}} for two-neutrino positron double-{beta} decay modes {beta}{sup +} EC/ECEC are calculated for {sup 74}Se, a nucleus of current experimental interest, using the deformed shell model based on Hartree-Fock states and employing a modified Kuo interaction in ({sup 2}p{sub 3/2}, {sup 1}f{sub 5/2}, {sup 2}p{sub 1/2}, {sup 1}g{sub 9/2}) space. The calculated half-life for the ECEC mode is {approx}10{sup 26}yr, and it may be possible to observe this in future experiments.
