Abstract:
Molecular dynamics simulations have been performed for the collision of C
60 with a graphite(0001)surface utilizing two kinds of interaction models. At the impact energy of 90eV and 150eV, the C
60 defroms severely and then returns to its sphere-like shape and rebounds without dissociation. The extremely stability and inelastic property of C
60 molecules during the surface scattering have been reproduced. In addition, the calculated final center-of-mass kinetic energies of the rebounding C
60 in both models are in good agreement with experimental results.
