GAMMA-RADIOLYSIS OF C-60-CENTER-DOT UV AND MASS-SPECTROMETRIC ANALYSIS

The gamma-radiolysis of C-60 in heptane and toluene solutions is studi ed for various doses. The radiation chemical yields G(-C-60) are calcu lated from the intensity decrease of absorption lines in the UV and vi sible spectra of the solutions. Judging from the results, C-60 is more stable in toluene than in heptane. It is suggested that C-60 is more stable in aromatic solvents. Peaks with masses 810-813 are observed fo r C-60 in toluene in the mass spectra of both unirradiated and irradia ted samples. These correspond to the masses of the proposed C-60-tolue ne complexes.
