A model of a neutrinoless 2\b{eta}-decay was proposed which predicted a shift of the 2\b{eta}0{\nu}-signal from the Q value (2\b{eta}-decay energy). The appearance of the shift was explained by a simultaneous total change in the 2\b{eta}0{\nu}-process of both the nuclear level structure and the structure of electron shells. It was supposed also that two virtual processes were presented in the neutrinoless 2\b{eta}-decay. There was postulated a virtual excitation of the product nuclei 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\b{eta}0{\nu}-decay has been experimentally observed ten years ago.
