Structure of excited states of unstable nuclei studied with antisymmetrized molecular dynamics

摘要

We study the structure of the excited states of unstable nuclei with variational calculations after spin parity projection in the framework of antisymmetrized molecular dynamics (AMD). The theoretical results reproduce energy levels of the excited states of C-12, Be-10 and Be-12. In the results of excited states both shell-model-like and clustering aspects appear. The valence neutrons play important roles for the development of the clustering structure in Be isotopes. [References: 5]
