| Research Abstract |
We studied the nuclear structure of axially symmetric deformation of samarium isotopes and tri-axially deformed states of neutron-rich xenon, barium isotopes based on the nuclear shell model. In medium-heavy nuclei, the conventional diagonalization method utilizing the Lanczos method is infeasible due to the huge size of the Hilbert space. In order to overcome this difficulty, we applied the Monte Carlo shell with quasi-particle-vacuum basis and the energy-variance extrapolation in the Monte Carlo shell model with Slater-determinant basis, and demonstrated that they work well in studying the nuclear structures of medium-heavy nuclei in which the pairing correlation is important.
