Abstract
In this paper a microscopic approach to calculation of the nuclear matrix element for neutrinoless double- decay with an account for nuclear deformation is presented in length and applied for , , and . The proton-neutron quasiparticle random-phase approximation with a realistic residual interaction (the Brueckner matrix derived from the charge-depending Bonn nucleon-nucleon potential) is used as the underlying nuclear structure model. The effects of the short-range correlations and the quenching of the axial vector coupling constant are analyzed. The results suggest that neutrinoless double- decay of , to be measured soon by the SNO Collaboration, may provide one of the best probes of the Majorana neutrino mass. This confirms our preliminary conclusion in Fang et al. [Phys. Rev. C 82, 051301(R) (2010)].
