由液态金属结构因子计算得到的有效原子间相互作用势与赝势微扰理论计算得到的有效原子间相互作用势不同。碱金属的nu eff(r)- nu ps(r)之差可能很小,为负值,但对于多价金属,它应该是很大的正值,并导致nu eff(r)相对于nu ps(r)的第一个最小值减小,以及随后的最大值增加。
The effective interatomic potential nu eff(r) as found from the observed liquid metal structure factor is different from that nu ps(r) calculated via pseudopotential perturbation theory. The difference nu eff(r)- nu ps(r) is likely to be small and negative for the alkalis but for polyvalent metals it should be substantial and positive and give rise to a diminished first minimum in nu eff(r) relative to nu ps(r) as well as an enhanced subsequent maximum.
