Abstract
The irradiation effects of C60 films induced by 0.98 GeV Fe ions at the same electronic energy loss of 3.5 keV/nm and different irradiation dose ranging from 5×1010 to 8×1013 ions/cm2 ， were analyzed by Raman scattering and Fourier transform infrared (FTIR) spectroscopes. The analysis results indicate that the irradiation results in a molecular polymerization and destruction of the C60. The partial recovery of the damage at the intermediate value of irradiation dose， 1×1012 ions/cm2， was caused by an annealing effect of electronic energy loss. The ion track or damage crosssection σ deduced from the Raman data was 1.32×10-14 cm2.
