Structures of light unstable nuclei, Li, Be, B, and C isotopes are systematically studied with a microscopic method of antisymmetrized molecular dynamics. The theoretical method is found to be very useful to study ground and excited states of various nuclei covering unstable nuclei. The calculations succeed to reproduce many experimental data for nuclear structures; energies, radii, magnetic dipole moments, electric quadrupole moments, transition strength. In the theoretical results it is found that various exotic phenomena in unstable nuclei such as molecular-like structures, neutron skin, and large deformations may appear in unstabel nuclei. We investigate the structure change with the increase of neutron number and with the increase of the excitation energies, and find the drastic changes between shell-model-like structures and clustering structures. The mechanism of clustering developments in unstable nuclei are discussed.

Cluster-shell competition in light nuclei

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 8 Be, 10 Be, and 10 B become larger by about 1-2 MeV by adding shell-model-like basis states to the ␣ + ␣ + N + N +¯basis states, the ␣ -␣ structure is a dominant configuration of the ground states. However, ␣-breaking wave functions strongly mix in 12 C, and the decrease of the energy from the 3␣ configuration by about 6 MeV is a clue to resolving a long-standing problem of the binding energies of 12 C and 16 O. 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.

“…In order to confirm the userfulness of the method, we apply this approach for the first time to the study of excited states of 12 C using finite range interactions. Concerning the formulation of AMD, the reader is refered to papers [8,9,10]. An AMD wave function is a Slater determinant of Gaussian wave packets;…”

Variation after Angular Momentum Projection for the Study of Excited States Based on Antisymmetrized Molecular Dynamics

1998

In order to study the structure of excited states we perform a variational calculation after spin parity projection (VAP) within the framework of Antisymmetrized Molecular Dynamics (AMD). The framework is proven to be a new powerful approach for the study of the various structures of excited states because it is free from model assumptions such as inert cores, existence of clusters, and the axial symmetry. By using finite range interactions with a density dependent term we reproduce well all the energy levels below 15 MeV in 12 C. This is the first theoretical model that reproduces many E2 transition rates and β decays to 12 C successfully.
