The C60 films have been implanted with 120—360 keV H,N, Ar and Mo ions by using a 200 keV heavy ion accelerator. The samples were investigated by Raman spectra. The results showed an exponential decrease of intensity for 1469 cm-1 line depending on the kind of ions and dose. There appeared a structural transformation of C60 to amorphous carbon at certain doses, which is correlated to the nuclear energy transfer. H ions implantation resulted in an asymmetrical broadening of 1469 cm-1 line, which is due to the electronic energy transfer.
