Abstract

The problem of neutral hydrogen outside a perfectly conducting plane surface is re-examined in an approximation in which the interaction potentials, derived from quantum electrodynamics, take a pure image form and the distance R of the proton from the surface is treated as a parameter rather than a dynamical variable. The numerically evaluated eigenfunctions and eigenvalues vary from the normal hydrogenic form for R → ∞ to a form in which the electron is considerably delocalised with a smaller binding energy. The results are expected to hold only for R > Rc ∼ 3 Bohr radii, but the deviations from the hydrogen results are much greater than could be found by perturbation theory.
