A. Savin et Hj. Flad, DENSITY FUNCTIONALS FOR THE YUKAWA ELECTRON-ELECTRON INTERACTION, International journal of quantum chemistry, 56(4), 1995, pp. 327-332
Short-range nonclassical electron-electron interaction is described by
a density functional in a scheme that allows multideterminant wave fu
nctions. The parameter that determines the coupling with the configura
tion-interaction-type calculations can be chosen in a controlled manne
r. Results are presented for the He and the Be series using a Yukawa-t
ype interaction. (C) 1995 John Wiley & Sons, Inc.
