摘要
在微观Vlasov方程的框架下,研究了^(11)Li核的巨偶极共振。正常的及软巨偶极共振的计算结果都与实验值较好地符合。这两种模式对平均场自旋-轨道耦合力的依赖都十分敏感。而^(11)Li中子晕的分布仅对软巨偶极共振有着十分重要的效应。同时也讨论了中子分离能的影响。
Giant dipole resonances (GDR) in nucleus ^(11)Li have been studied within a microscopic Vlasov approach. A quite fair agreement with the experimental value is found. The results for both normal and soft modes are very sensitive to the spin-orbit coupling in mean field, while the soft mode is quite dependent on the extension of neutron halo in ^(11)Li. The effects of separation energy of one neutron are also discussed.
