扩展Skyrme力的自洽半经典计算与原子核静态及Isoscalar巨共振性质

SELFCONSISTENT SEMICLASSICAL CALCULATION WITH EXTENDED SKYRME FORCES AND THE PROPERTIES OF ISOSCALAR GIANT RESONANCES

从扩展Skyrme力的HF能量密度■(r)出发,利用半经典近似下动能密度泛函τ_q[ρ_n,ρ_p]及自旋-轨道密度泛函J_q[ρ_n,ρ_p],得到了核系统的能量密度泛函■[ρ_n,ρ_p].在给定核子数条件下对此泛函作变分计算使我们确定了核的基态密度分布,由此研究了原子核的静态及isoscalar巨共振性质.所有结果同实验及HF(RPA)计算结果很好一致.

The HF energy density functional [ρ_n, ρ_p] is obtained by utilizing the kinetic energy density functional τ_q[ρ_n, ρ_p] and spin-orbit density functional [ρ_n, ρ_p] in semiclassical approximation. The nuclear ground state densities are determined by varying the functional with respect to ρ_n and ρ_p under certain conditions. A series of nuclear static and isoscalar giant resonances properties are evaluated with above determined densities. All the results are in good agreement with experimental and HF (RPA) ones.
