摘要
从扩展Skyrme力出发,利用自洽半经典(Scsc)方法确定了热核^(40)Ca和^(208)Pb的核子密度_(ρq)(q=n,p);由核物质近似及定域密度近似(LDA)推导了有限温度微观光学势的计算公式.利用这些公式及上述密度,具体计算了不同能量和温度下的核子-核光学势.这样得到的光学势是完全自洽和微观的,并且较完整地考虑了温度对光学势的影响.本文仅讨论光学势的实部.
The nucleon densities ρ_q of ^(40)Ca and ^(208)Pb determined by finite temperature self-consistent semiclassical calculation are utilized together with nuclear matter approach and local density approximation to evaluate the nucleon-nucleus optical potentials at finite temperature. The self-consistency and the temperature effect have been better taken care of by the present approach.
