We have calculated the lifetimes of the two-neutrino and neutrinoless double-positron decay, K-capture, and KK-capture processes for several nuclei. It is found that the two-neutrino KK-capture process is a dominant channel with a lifetime of 10/sup 23/--10/sup 24/ yr, whereas the neutrinoless processes have lifetimes greater than 10/sup 27/yr if the currently accepted upper limits on the lepton-number-violation parameters are used.
