摘要
从同一扩展Skyrme力出发,用自洽半经典方法确定球形核基态密度分布ρ_n和ρ_p,用Sum rule方法计算强度函数矩m_(-1)~λ,m_1~λ和m_3~λ,从而具体计算了isovector巨单极,巨偶极和巨四极共振的平均激发能量,以及isoscalar巨单极和巨四极共振的宽度,部分结果同实验事实做了比较.
The average energies of isovector giant resonances and the widths of isoscalar giant resonances are evaluated with the help of a selfconsistent semiclassical Sum rule approach. The comparison of the present results with experimental ones justifies the self consistent semi classical sum rule approach to the average properties of giant resonances.
