Effect of medium-energy radiation on C-60 films

C-60 films were irradiatied at room temperature by medium-energy (120-360 k eV) radiation of different ions (H+, He+, N+, Ar+), and the radiation effec ts were investigated using Raman spectra. The results showed that the radia tion of medium-energy ions could cause C-60 films polymerized and amorphous . However, occurrence of the phenomena depends on dosage, which is related to the interaction between the radiation ion and C-60 molecule. A possible explanation for the experimental results is given and the mechanism of the interaction between the radiation ion and C-60 molecule is discussed.
