概要 We calculate nuclear matrix elements (NMEs) around mass 130 for the neutrinoless double beta decay, making use of the wavefunctions obtained by diagonalising an extended pairing plus quadrupole effective interaction in the nuclear shell model. In order to see the dependence of wavefunctions on NMEs, the NMEs are also calculated by the pair-truncated shell-model. Furthermore, the NMEs are also calculated in the shell model by artificially increasing the strength of the monopole pairing interaction. The results are consistent with those previously obtained in the shell model calculations for the mass 76 and 82 isotopes.
