Abstract
Local variations in the reactivity of NO on the Ru(0001)-(I x 1)H surf ace have been probed with a supersonic molecular beam. The presence of adsorbed hydrogen atoms creates an elastic scattering channel in the specular direction, concomitant with a suppression of the initial stic king probability. Argon is scattered in a qualitatively similar, but i nstrumentally limited, specular peak from the same surface. The well c haracterized position of the hydrogen atoms allows the scattering to b e related to collisions at the threefold hollow sites within the surfa ce unit cell.
