| Research Abstract |
We have developed new effective interactions based on the microscopic nucleon-nucleon interaction. After confirming that the level inversion in the calcium isotopes is quantitatively reproduced by the self-consistent mean-field calculations using these interactions, we have investigated shell structure of spherical nuclei in wide mass range from medium-mass to super-heavy nuclei, and have found several cases in which new magic numbers specific to unstable nuclei may emerge. We have also investigated Coulombic effects on the nuclear pairing, properties of low-energy excitations, and transition from spherical to deformed nuclei.
