| Abstract: | We demonstrate whether the cluster structure dissolves or remains when the shell-model-like model space is introduced in addition to the cluster model space in light nuclei. Although the binding energies of 8Be, 10Be, and 10B become larger by about 1–2 MeV by adding shell-model-like basis states to the α+α+N+N+ ・・・basis states, the α-α structure is a dominant configuration of the ground states. However, α-breaking wave functions strongly mix in 12C, and the decrease of the energy from the 3α configuration by about 6 MeV is a clue to resolving a long-standing problem of the binding energies of 12C and 16O. The improved version of antisymmetrized molecular dynamics (AMD), AMD superposition of selected snapshots (AMD triple-S), is used to show the cluster-shell competition of these nuclei. |
