The second-order perturbation corrections to the energy computed using the optimized effective potential (OEP) arising from single-particle excitations are computed explicitly for a number of closed-shell atoms. It is found that almost all of the difference between the Hartree-Fock energy and the OEP energy is recovered in second order.
