Abstract
The energies of an electron above a liquid-helium surface are analyzed in t erms of an electron-atom polarizability potential with an infinite barrier. An integration over a layer, and a summation over different layers, leads to a one-dimensional Coulomb potential with a l/x(2) correction. This poten tial provides an accurate description of the observed one-dimensional Rydbe rg energies with a quantum defect.
