Outline of Final Research Achievements

In this study, I investigated the radii and deformation of neutron-rich nuclei. I also focused on the neutron halo which can be formed in the drip-line nuclei. I employ the theoretical model of antisymmtrized molecular dymamics and studied various isotopes. The obtained results are follows. (1) The relationship between the nuclear deformation of neutro-rich nuclei and the increase of the reaction cross section was found. (2) It was found that several nuclei such as 37Mg may have neutron-halo. (3) The relationship between the development of clustering and the increase of charge changing cross section was pointed out.
