- 論文の詳細を見る
Spatially correlated modes of the extra four particles in the core plus four-particle system are investigated on the basis of the (major-shell-mixing) shell-model picture. New bases of the four-body configurations are introduced to represent both the shell-model character and the α-like-clustering nature of the four particles. The bases define a subspace in which the single-particle shell-model states are vertically truncated with the [4] symmetry. The model is applied to the study of the low-lying even-parity levels of ^<20>Ne, reproducing well the levels in the ground band with the use of the residual interaction much weaker than that used in the sd shell model. Spatial correlations and higher-shell-mixing effects in the calculated states are investigated from the various viewpoints.
