The reaction of C{sup +} with C{sub 60} has been studied under single collision conditions over the energy range from 2 to 78 eV. C{sub 61}{sup +} is observed to form with no activation energy and survives for > 1 ms at excess energies up to 10 eV. At low collision energies the dominant C{sub 61}{sup +} decay pathway is to C{sub 60}{sup +} + C, which can also result from charge transfer. These two C{sub 60}{sup +} production mechanisms can be distinguished by the different C{sub 60}{sup +} velocity distributions which result. {sup 13}C labeling clearly demonstrates that in the C{sub 61} {sup +} adduct, the {sup 13}C{sup +} projectile undergoes exchange with C atoms in the C{sub 60} target. At collision energies above 20 eV, a series of C{sub 60-2n} {sup +} products are observed, and {sup 13}C labeling shows that C-atom exchange also occurs in collisions leading to these fragmentation channels. At high collision energies a small amount of C{sub 59}{sup +} is detectable, but no other odd-sized fragments were detected. 19 refs., 2 figs.
