摘要：
The accuracy of the recently developed correlation energy functional of Wilson and Levy is investigated. The correlation contributions to first ionization potentials of first-row atoms, hydrides and dimers, as well as the contributions to the dissociation energies of neutral and ionic hydrides and dimers are calculated and compared with experimental values. It is found that the functional developed by Wilson and Levy represents a positive step in the way to improve the accuracy of density functional models.
