The oxidation of the Ni(111) surface by a supersonic atomic oxygen beam has been quantitatively studied using in situ high-resolution electron-energy-loss spectroscopy. For a room temperature substrate, a drastically different oxidation rate is observed for atomic oxygen induced oxidation than for molecular oxygen based oxidation. This rate was found to be two orders of magnitude higher than that...
