摘要: From the Fermi theory of $\ensuremath{\beta}$-disintegration probability simultaneous emission two electrons (and neutrinos) has been calculated. The result is that this process occurs sufficiently rarely to allow a half-life over ${10}^{17}$ years for nucleus, even if its isobar atomic number different by 2 were more stable 20 times electron mass.
