  author={Vadim A. Rodin and Amand Faessler and Fedor {\vS}imkovic},
The nuclear matrix elements M of the neutrinoless double beta decay (0νββ) of most nuclei with known 2νββ-decay rates are systematically evaluated using the Quasiparticle Random Phase Approximation (QRPA) and Renormalized QRPA (RQRPA). The experimental 2νββ-decay rate is used to adjust the most relevant parameter, the strength of the particle-particle… CONTINUE READING
