基于赝势理论导出的有效电对势、改进的超网链（MHNC）近似中计算的静态结构因子和粘弹性近似中的动态结构因子，我们研究了膨胀液态铷的动态结构的温度依赖性，特别是集体激发的色散关系。所观察到的色散关系的温度依赖性的特征在理论上得到了很好的再现。
We have investigated the temperature dependence of the dynamical structure, in particular the dispersion relation of the collective excitation, of expanded liquid rubidium on the basis of the effective pair potential derived by the pseudopotential theory, the static structure factor calculated in the modified hypernetted-chain (MHNC) approximation and the dynamical structure factor in the viscoelastic approximation. The characteristic features of the observed temperature dependence of the dispersion relation are well reproduced theoretically.
