| Abstract: | The Goldhammer—Feenberg variational procedure is applied to the perturbation treatment of the configuration interaction matrix of Diner, Malrieu and Claverie (PCILO) to yield a scheme (PVCILO) that appears more accurate for the small systems investigated. In addition, PVCILO shows promise as executing as an N2 method, where N is the number of basis bonds. |
