Abstract

We have studied the structures of He isotopes, ⁸B, and ⁹C by using an extended framework of antisymmetrized molecular dynamics, which is designed to describe the halo structure and the core excitation simultaneously. The effectiveness of the present framework in describing the halo structure is demonstrated in the calculated results of He isotopes. The structures of ⁸B and ⁹C are discussed focusing on the halo structure and the core excitation in these nuclei. We have found the cluster structures in the cores of these nuclei, which plays an important role in explaining the observed physical quantities.
