The two-neutrino double [beta] decay matrix elements of [sup 58]Ni, [sup 96]Ru, [sup 106]Cd, and [sup 136]Ce are calculated in the framework of the quasiparticle random phase approximation and the corresponding double [beta][sup +]/electron-capture (EC) decay ([beta][sup +][beta][sup +]/[beta][sup +]EC/ECEC) half-lives are estimated. The calculated ground-state-to-ground-state half-lives range from 3.9[times]10[sup 23] to 6.4[times]10[sup 19] yr indicating that the double [beta][sup +]/EC decay could, in principle, be detected using currently known experimental techniques.
