Abstract
Positively and negatively charged coalescence products of C60 and C70 were characterized following pulsed laser desorption from fullerene th in films. Coalescence occurs by gas-phase reactions. Positive ions are generated by thermoionization of hot neutrals, while negative ions li kely form by electron attachment to neutral species in the outermost r egion of the desorption plume. Thermoionization rate and surface-induc ed dissociation (SID) measurements are consistent with fullerene-like structures for coalescence products detected as positive ions.
