Abstract
The adsorption probability of xenon on Pt(110)(1 x 2) shows a strong d ependence on both the polar (theta(i)) and aximuthal angles of inciden ce. For atoms incident along the (110BAR) direction the adsorption pro bability increases slowly with increasing angle of incidence, scaling as E(i) cos0.5theta, whereas along the (100) azimuth it decreases with increasing angle of incidence, exhibiting ''negative'' energy scaling . The hard cube washboard model does not account quantitatively for th ese differences with a single consistent set of parameters.
