Abstract
Electron densities and effective potentials at a jellium surface are calculated using the local-density (LD) approximation inside the metal and a physically based interpolation to the image potential outside. The image-plane position is also determined self-consistently, and we find only a slight contraction of with respect to the LD values of Lang and Kohn. We also provide an empirical criterion to determine from the local density.
