Results of the Hartree-Fock-Wigner model for He2 and LiH using an atomic and a molecular parameterization of the correlation kernel are presented and interpreted in terms of Wigner intracules. The purely atomic parameterization turns out to be insufficient for molecules and is replaced by a fit along the potential curve on a per-molecule basis. It is argued that the remaining shortcomings partly result from the restriction of the currently used correlation function to be symmetric in relative...[Show more]
