Impingement of O16-atoms on an O218 covered Pt(111) surface at 77 K induces the evolution of gas-phase O218 and O16O18 in a ratio of ∼4:1 independent of atomic flux or kinetic energy. The total initial probability of desorption of molecular oxygen induced by impingement of atomic oxygen is measured as a function of incident O-atom flux, kinetic energy, and angle. Interestingly, the probability is found to depend on incident angle with values ranging from 0.25±0.02 for a 60° angle of incidence to 0.42±0.02 for normal incidence.
