Abstract

The laterally averaged physisorption potentials of He and Ne on noble metal, graphite, and MgO surfaces are calculated with a modified Gordon-Kim (G-K) method. Each of the energy terms in the electron gas formula is slightly modified to include the inhomogeneity effects of the system. Overall, our results show this to be a simple way of predicting potentials that are reasonably consistent with experiments. The orientationally anisotropic H₂/metal physisorption potential is also investigated and compared with experiments.
