FORMATION OF ENDOHEDRAL CARBON-CLUSTER NOBLE-GAS COMPOUNDS WITH HIGH-ENERGY BIMOLECULAR REACTIONS - C60HEN+ (N = 1,2)

Results are reported for high-energy beam studies of the formation of adduct ions in the reactions of C60+. and C60(2+) with He and D2 in a four-sector mass spectrometer. Studies of the addition of He to C60+. at translational energies of 2, 3, 4, 5, 6 and 8 keV showed optimal adduct formation from 5 to 6 keV. The C60He2+ adduct was observed in collions between C60(2+) and He at 6 keV translational energy. No adduct formation was observed between D2 and C60+. or C60(2+) at 6 keV translational energy.
