Abstract
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.Keywords
