Abstract
Effective pair potentials for liquid Na and liquid K have been calculated by combining previous X-ray structure data with the Born-Green, Percus- Yevick and hypernetted chain integral equations. It is concluded that reliable ion-ion potentials, in good overall agreement with recent pseudopotential calculations, can be obtained from the hypernetted chain equation. Contrary to earlier suggestions, the Born-Green theory does not appear to be applicable to liquid metals.Keywords
