英文摘要Nuclear double beta(-)-decays with two neutrinos were observed for many years and a systematic law describing the relation between their half-lives and decay energies was also proposed recently [Phys Rev C, 2014, 89: 064603]. However, double beta(+)-decay (beta(+)beta(+)) with emission of both two positrons and two neutrinos has not been observed up to date. In this article, we perform a systematic analysis on the candidates of double beta(+)-decay, based on the 2012 nuclear mass table. Eight nuclei are found to be the good candidates for double beta(+)-decay and their half-lives are predicted according to the generalization of the systematic law to double beta(+)-decay. As far as we know, there is no theoretical result on double beta(+)-decay of nucleus Dy-154 and our result is the first prediction on this nucleus. This is also the first complete research on eight double beta(+)-decay candidates based on the available data of nuclear masses. It is expected that the calculated half-lives of double beta(+)-decay in this article will be useful for future experimental search of double beta(+)-decay.
