Theory of Thermal Energy He Scattering From Adsorbates. Gumhalter, B. Volume 40. Theory of Thermal Energy He Scattering From Adsorbates, pages 148-155. 1988. Website abstract bibtex The main goal of the present chapter has been to confirm that the scattering cross section for the He → CO/Pt(111) collision event is largely determined by the long-range He-adsorbate van der Waals (vdW) potentials. The He → CO/metal collision event is governed by the direct or bare potentials, occurring also in the gas phase scattering, and the surface mediated potentials that arise because of the proximity of the third polarizable body—that is, the surface, whose presence modifies the simple, two-body gas phase interactions. This is expected to be of particular importance in the case of long-range vdW interactions and much less so in the case of short-range potentials. The repulsive He–CO potentials are known from semi-empirical calculations and the present chapter uses the loaded sphere (LS) He–CO repulsive potential. Furthermore, throughout the calculations it is assumed that the polarizability of the substrate surface has a negligible effect on the repulsive short-range potential between He and adsorbed CO, which is in accordance with the present experience. On the other hand, the attractive long-range vdW He-adsorbate potential undergoes significant modifications. The effect of the surface on the strength of the He-adsorbate vdW potential is two-fold and arises from the physisorptive and chemisorptive bonding of the adsorbate to the substrate.
