抜粋

Covariant density functional theory is used to investigate quantum shape fluctuation in 16C and other even-even carbon isotopes. Long-range correlations beyond the mean-field approximation are taken into account by configuration mixing of wave functions with triaxial shapes and by restoring the spontaneously broken rotational symmetry through a three-dimensional angular-momentum projection. The systematics of the excitation energy of the 21+ state and the B(E2:21+→01+) values in carbon isotopes are reproduced rather well. Decoupled structures with rather different deformations for neutrons and protons have been found in 16,18,20C. In addition, the effects of shape fluctuations in β and γ deformations on the low-lying excited states of these nuclei are examined.
