The potential energy function V(r) is constructed for a He atom in the vicinity of a Ne-plated surface of graphite. This function includes He-Ne pair interactions, triple dipole He-Ne-Ne interactions, a McLachlan-type He-Ne-graphite interaction, a theoretical He-graphite potential, and a contribution from the Ne atomic vibrations. The Schrödinger equation is solved to derive the He scattering bound-state resonance positions and the energy-band structure E(K). The specific heat and isosteric heat are computed and compared with data of Crary and Vilches and of Hanono and Lerner, respectively.
