Abstract
Tight approximations to the electron-pair density h(u) of atomic systems ar e 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 accur acy of the approximations is analyzed for two- and four-electron systems. ( C) 1999 Published by Elsevier Science B.V. All rights reserved.
