| Research Abstract |
In order to understand "interdependence of the G-matrix interaction and the cluster structure in nuclei", we have studied the mechanism of clustering of nuclear states based on the G-matrix interaction for a realistic nuclear force. In 2010, we have shown that theα-αcluster structure of the^8Be nucleus can be explained by the state-dependence of the tensor force. In 2011, it has been shown first in the world that both of the shell structure in the ground state and the 3αcluster structure in the excited 0^+state of^<12> C can be reproduced by the Brueckner-AMD calculation based on the realistic nuclear force.
