摘要
利用自洽半经典(SCSC)计算确定的基态核子分布,讨论了电模式isovector巨共振性质.特别是,我们不仅考虑了△T_3=0的模式,而且考虑了△T_3=±1模式,从而讨论了此类巨共振的同位旋性质,给出了它们的增强因子及Centroid能量的同位旋分裂.其中增强因子和HF+RPA计算结果相一致,而Centroid能量的同位旋分裂则和实验事实相近.
The properties of isovector giant resonances are discussed with the help of the nuclear ground state density profiles obtained from self consiotent semi-classical calculation. Both the component with △T_■=0 and the components with △T_■=±1 are considered. The isospin properties of the giant resonances are thereby studied. The results are in good agreement with HF + RPA calculation and experimental evidences.
