Abstract In a special case of the Löwdin-Adams variant of perturbation theory, knowledge of the perturbed wavefunction through first order is sufficient for the calculation of the energy correct to the fifth order. This is applied to the split-shell wavefunctions of H−, He, and Li−. The results are presented, compared with other approaches, and discussed.
