A perturbation variation treatment of two‐electron atoms using exp (–α r < – β r > ) as the zeroth order wave function is presented. The parameters α and β are variationally determined and the results are compared with the “physical” choice α = Z , β = Z – 1, and with Z −1 theory. The energy is given through fifth order in the perturbation.
