| 英文摘要 | A new set of Nilsson parameters, with the isospin-dependent spin-orbit potential (K) and 12 term (it), is proposed for neutron-rich nuclei of Ne and Mg isotopes. The ground-state deformations and B(E2) values of Ne and Mg nuclei around N = 20 are studied within the framework of the macroscopic-microscopic (MM) model with the new set of Nilsson parameters. The calculated results are compared with the experimental data. The experimental large deformations and B(E2) values are well reproduced by the new calculation of this paper. The calculated results are also compared with the recent results of mean-field models and shell models. Detailed discussions of the shell structure around N = 20 are given. It is predicted that the enhanced negative shell correction energies at deformed shape and the weak N = 20 magic shell closure lead to the large deformations for Ne and Mg nuclei around N = 20. |
