Abstract:

Correlation-relaxation corrections to electronic transition energies are obtained through the self-energy fields for the particle-hole propagator. These objects are generated from Feynman-Dyson like equations within the scenario of the superoperator algebra. A Hartree-Fock reference state and a partition of the operator space along with a particle conserving manifold are used to recast the lower order perturbative expressions for the self-energies. Correlated states are used to make explicit the appearance of higher order correction terms to the self-energy. It is explicitly shown that the present scheme leads to a proper classification of the order of the contribution from both the intrinsic interaction operator and the improved reference state. © 1995.
