Abstract
The wave functions, which correspond to a surface potential barrier having Friedel oscillations, behave nonanalytically as a function of energy in the neighborhood of the Fermi energy. A prescription is given which isolates the nonanalytic behavior in a normalization constant and which permits the straightforward numerical evaluation of the wave functions.Keywords
