Abstract
Cluster aspects in light unstable nuclei as well as light stable nuclei are discussed. We focus on cluster structures of excited states in 12C, 9Li, and 10Be. The rotation of 3α cluster gas states in 12C and the 6He+t cluster resonances in 9Li are theoretically studied.
Highlights
In the recent experimental and theoretical studies, it has been revealed that a variety of cluster structures appear in unstable nuclei as well as stable nuclei
Shell-model structures and cluster formation in low-lying states as well as developed cluster structures in excited states can be described within the antisymmetrized molecular dynamics (AMD) framework without assuming the existence of any clusters
The ground state of 12C is the compact triangle state of the 3α cluster structure with a mixing of the p3/2-shell closed configuration, while 3α cluster structures develop in excited states especially near or above the 3α threshold energy
Summary
In the recent experimental and theoretical studies, it has been revealed that a variety of cluster structures appear in unstable nuclei as well as stable nuclei (for instance, Refs. [1,2,3,4] and references therein). The coexistence of cluster and mean-field features brings rich phenomena in nuclear systems. The energy for the 3α cluster excitation is much smaller than the energy for the nucleon gas state, implying that the mean-field and cluster states coexist in low-energy spectra of 12C. We discuss cluster phenomena in p-shell nuclei based on the theoretical calculations mainly using the antisymmetrized molecular dynamics (AMD) method [3,9]. One the advantages of the AMD method is that the model can describe features of both cluster and mean field aspects in general nuclei. Shell-model structures and cluster formation in low-lying states as well as developed cluster structures in excited states can be described within the AMD framework without assuming the existence of any clusters.
