Abstract Short‐range nonclassical electron‐electron interaction is described by a density functional in a scheme that allows multideterminant wave functions. The parameter that determines the coupling with the configuration‐interaction‐type calculations can be chosen in a controlled manner. Results are presented for the He and the Be series using a Yukawa‐type interaction. © 1995 John Wiley & Sons, Inc.
