T. Leininger et al., COMBINING LONG-RANGE CONFIGURATION-INTERACTION WITH SHORT-RANGE DENSITY FUNCTIONALS, Chemical physics letters, 275(3-4), 1997, pp. 151-160
A density functional for short-range electron-electron interaction rec
ently developed by one of us, has been implemented into a multi-refere
nce configuration-interaction code with explicit treatment of long-ran
ge interaction only. Possible advantages of such an approach are discu
ssed, using as examples some closed-shell atoms (Be, Ne) and diatomics
(H-2, Li-2, C-2, N-2, F-2). (C) 1997 Published by Elsevier Science B.
