Abstract
The exoemission in the reaction of O-2 with Cs surfaces is found to depend strongly on the translational energy of the impinging O-2 molecules. Seeded beam experiments show that in the initial oxidation state exoemission increases with increasing O-2 velocity. Above 0.5 eV of kinetic energy the increase is found to be proportional to exp(-v*/v) with a value v* of 1.6 x 10(4) m/s.File in questo prodotto:
