G. it is up to 80 eV when the cluster plane is parallel to the surface. In addition, the impact induced adsorption of C〓 cages was studied in detail. After impacting, the normal incident C〓 was found to move laterally on the surface due to the anisotropic interaction between the dimerized surface and the cage. Finally, it resided on the top of a dimmer or in the trough, which are the energy favored adsorption sites.
