Abstract

Abstract Tight approximations to the electron-pair density h( u) of atomic systems are obtained in terms of a very limited set of values of the total scattering intensity K( k), by means of the minimum-cross-entropy technique. The accuracy of the approximations is analyzed for two- and four-electron systems.
