Abstract
In a recent paper we presented the analytical asymptotic structure of the Kohn-Sham exchange potential in the classically forbidden region a t a metal-vacuum interface. This result is valid for self-consistently determined orbitals of the semi-infinite jellium and structureless-ps eudopotential models of a metal surface. In this paper we provide the details of our derivation. The correctness of the analytical derivatio n is further substantiated through numerical work.
