A model of a neutrinoless 2\beta-decay was proposed which predicted a shift of the 2\beta0ν-signal from the Q value (2\beta-decay energy). The shifts were calculated for 76Ge (ΔE=-2.6 keV), 100Mo (ΔE=-4.7 keV), 130Te (ΔE=-3.7 keV). An appearance of the shifts was explained by an excitation of atomic shells of the product atom, with the following de-excitation by emission of X-rays. A virtual excitation of the product nuclei was supposed in an addition to exchange with a virtual neutrino between the two decaying neutrons. A comparison with the H-M and Cuoricino data has strongly supported the validity of the proposed model. It pointed out also that the 2\beta0ν-decay has been experimentally observed ten years ago.
