Comparison with the full exchange shows significant improvement over the local-density form. An interpolation between the surface-plasmon-dominated small-wave-vector contributions and the nonlocal correction for large q is suggested, and some of the difficulties inherent in this method are discussedExchange interactions (electron)Metal theoryPlasmonsSurface electron statesSurface energyarticle2183158
