Abstract
A method which combines features of the WCA and RPA approximations is proposed for calculating an effective interatomic pair potential from an observed structure factor. The method is tested on Ne and gives a plausible result; it is then applied to Al, In and Pb and for this sequence there is evidence of the increasing importance of many-ion and density-dependent forces.Keywords
