An excess of events in the beta spectra of samples enriched with 100Mo isotope compared with the spectra of samples with a natural concentration of a given isotope has been observed in the experiment on the search of the double beta decay of 100Mo. This result may be interpreted as the observation of a two-neutrino/?/? decay of 100Mo with a half-life Tm = (3.3 ίί£) X 1018yr.
