摘要：

C-60 fullerite films on Si substrates have been bombarded with H, He, C and Ar ions with energies between 60 and 600 keV and doses ranging from 1X10(12) to 5X10(16) cm(-2). Raman scattering showed structural changes of the fullerite depending on the ion species, energy and dose. At low doses a new line at 1463 cm(-1) in the Raman spectra indicates polymerization of C-60. At higher doses a broad and asymmetric line between 1000 and 1700 cm(-1) appears which is characteristic for amorphous carbon. The amorphization process is correlated with the nuclear energy deposition while electronic energy loss leads to polymerization of C-60.
