Single impact process of a C_<60> molecule and an argon cluster on a C_<60> film is studied by using molecular dynamics simulations in order to investigate the cluster radiation effects. The C_<60> molecule impacts on the C_<60> film with an acceleration energy ranging from 0.1 to 10 keV/molecule, and the carbon atoms around the impact-induced hole show amorphous-like binding morphology. The temperature around the impact point stays high for a remarkably long time due to the low heat conductivity based on the Van der Waals interaction, and the polymerization also expands in a long time scale. The argon cluster impact basically results in a similar result except for the bigger volume of the hole, which is proportional to the incident energy for both impacts.
