Thermal energy atom scattering (TEAS) is used to determine the initial sticking probability So for dissociative chemisorption of Oe on Ag( I 1 I ). Mixed beams of He and O2 are used to study Se as a function of energy of the molecule (MBTEAS) At thermal energies S, is about 3.5 x 10m6. It drops to i
We have measured the dissociative chemisorption probability of D2 on Pt ( I 1 I ) as a function of molecular oxygen coverage and have found that the dissociation probability decreases linearly with O2 coverage. The results suggest that O2 poisons the chemisorption sterically by blocking approximatel
