Surface Scattering of Hyperthermal (10-50 eV) Neutral C-60 - Angular and Energy-Distributions
The scattering dynamics of hyperthermal C-60 from a carbonized nickel surface at impact energies E(0)=10-50 eV was studied by high resolution angular and energy distributions. The scattered energy scales linearly with Eo and kinetic energy losses vary with scattering angle from similar to 85 to similar to 40%. Nearly complete decoupling between normal and tangential energy losses was found. The tangential losses are described in terms of various models of rotational excitation and the involvement of translational slip is concluded.
