A multidimensional potential energy surface for the interaction of a diatomic molecule with a metal surface is presented. The potential includes the effects of an activation barrier to the adsorption process which has a value changing with position within the surface unit cell. The model accounts for recent experimental data for the diffraction of H2 beams with energy in excess of the measured activation barrier. Wavepacket calculations for the diffracted intensities show features which should make H2 diffraction experiments a detailed probe of the reactive-potential topology.
