The nuclear matrix elements associated with the light Majorana neutrino mass mechanism of the neutrinoless double beta decay of 48Ca, 76Ge, 82Se, 96Zr, 100Mo, 116Cd, 128Te, 130Te, 136Xe, and 150Nd have been calculated within the self-consistent renormalized quasiparticle random phase approximation (SRQRPA). By following a recently proposed procedure, where data on the two-neutrino double β decay half-lives are used to derive appropriate value of the particle–particle strength of the nuclear Hamiltonian, we have found that the SQRPA results are comparable with those from the QRPA and the RQRPA approaches. This constitutes an additional argument in favor of the convergence of the QRPA-like results.
