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 ions in the reactions of C+.60 and C2+60 with He and D2 in a four-sector mass spectrometer. Studies of the addition of He to C+.60 at translational energies of 2,3,4,5,6 and 8 keV showed optimal adduct formation fro 5 to 6 keV. The C60He2+ adduct was observed in collisions between C2+60 and He at 6 keV translational energy. No adduct formation was observed between D2 and C+ 60 or C2+60 at 6 keV translational energy.
