Abstract

An atom or molecule far from a surface experiences an interaction V ~ -C₃z^-3, where z is the distance to the surface. We compute the coefficient C₃ for He, H, and H₂ interacting with a graphite surface. The calculation utilizes measured frequency dependent values of the polarizabilities and dielectric function. Comparison is made with C₃ values deduced from surface scattering and adsorption experiments.
