## Abstract It is shown that the determination of a unique scaling parameter, based on scale‐invariant forms for energy in the scaled zero‐order Hamiltonian approach of Feenberg, is not possible because the higher‐order invariants themselves are nonunique.
## Abstract The relation of the straightforward Rayleigh‐Schrödinger perturbation theory for the interaction of two atoms to the asymptotic exchange theory is described. The one‐electron case of a hydrogen atom perturbed by a nucleus is examined in detail. It is shown that the asymptotic theory con
