摘要：

High resolution photoemission studies of solid O2 in contact with multilayer films of C60 on solid substrates showed conversion to CO, CO2, carbonyl-like structures, and a carbon residue upon exposure to low energy and high energy photon sources. These processes are probably activated by the capture of a low energy electron to form the more reactive O2- species. These results reveal thermodynamically favored reaction processes but also kinetic limitations for our condensed structures. No reaction of O2 with C60 was observed without photoexcitation.
