Abstract
The Hellmann-Feynman sum rules for the planar surface of s-p-bonded metals modeled by a half-space-stabilized jellium are presented and numerically tested. They relate density derivatives of the (stabilized) bulk and surface energies to moments of the electric field appearing in the metal region, to the number of electrons spilled out into the vacuum region, and to the electronic density at the surface.
