| 概要 | The nuclear matrix elements (NMEs) for the neutrinoless double beta decays from 130Te to 130Xe and from 136Xe to 136Ba are calculated in the nuclear shell model. In order to investigate the model dependence on the NMEs, pair-truncated shell-model calculations are also performed. It is found that the NMEs are sensitive to the ground-state correlations. In particular, the isovector monopole-pairing interactions largely affect the NMEs. |
