O^++C"6"0". C"6"0O^+ production and decomposition, charge transfer, and formation of C"5"9O^+. Dopeyball or [CO∞#x0393;"5"8^+ - Christian, J.F.; Wan, Z.; Anderson, S.L. (Elsevier)
The reaction of O^+ with C"6"0 has been studied over a collision energy range from 2 to 77 eV. At collision energies below 10 eV, we observe formation of the metastable C"6"0O^+ adduct, as well as charge transfer and chemically driven fragmentation processes. As energy increases, the adduct decomposes to form C^+"6"0, C^+"5"9 and C^+"5"8. At higher collision energies, in addition to the expected series of C^+"6"0"-"2"n fragments, we observe odd-sized fullerene oxides, C"6"9"-"2"nO^+, n=0-4. These could be either O-substituted fullerenes (dopeyballs) or endohedral CO complexes of the form [CO∞#x0393;"5"8"-"2"n]^+. Our evidence is most consistent with the endohedral CO structure, which would be the first example of a molecule collisionally trapped inside a fullerene. We also examined collisions of CO^+ with C"6"0, however only C^+"6"0"-"2"n fragment ion production is observed.
