| Outline of Final Research Achievements |
Low-lying states for even-even, odd-mass, and doubly odd nuclei around masses 80, 100 and 130 are systematically investigated using a shell model. Energy levels of the low-lying collective states for even-even isotopes are reproduced very well along with electromagnetic transitions. For odd-mass and doubly odd nuclei, complicated level schemes and electromagnetic moments are in excellent agreement with the experimental data. Using wave functions obtained in these calculations, the nuclear matrix elements for the neutrinoless double beta decay are estimated. Our calculations give a few times smaller nuclear matrix elements than those obtained by other theoretical methods.
