| Abstract: | Ab initio calculations of the total scattering cross section for the collision system He → within the renormalized distorted wave Born approximation are reported. The interaction potential for this atom-adsorbate system consists of the usual two-body gas phase-like potential as well as two additional substrate mediated van der Waals contributions, all with similar long range behaviour. Comparison of the calculated cross sections for various incident velocities and angles with available experimental data is made without using any adjustable parameters in the potential to fit the data, and the importance of including the anisotropic and substrate-mediated forces is emphasized. |
