A systematic study of even–even nuclei from Ne to Ca in covariant density f…

The ground-state properties of even–even nuclei from Z = 10 to Z = 20 are systematically studied in covariant density functional theory with the point-coupling interaction PC-PK1. The triaxiality effect on nuclear binding energy, including the mean-field part and rotational correction energy, is examined.We find that 38Si, 46S, and 48S exhibit considerable triaxial deformation. The result…
