Notes:
A modified hard-cube model is employed to account for the recent experimental results of the Bernstein group on steric effects in the scattering of polyatomic molecules on a graphite (0001) surface. In the low surface temperature (Ts) limit simple analytical formulas are obtained for Ts dependences of the probability of direct scattering, the average postcollisional translational energy and the average tangent of the scattering angle. The model accounts for the surface temperature dependences of the scattering probability and the angular distributions of direct scattering over the whole surface temperature range. It also gives the experimentally observed functional dependence of the steric effect in scattering probability vs the surface temperature, but fails to give quantitative agreement.
