摘要：

An experimental study of the interaction of H2 with the Ag(110) surface is presented. The diffraction intensities, measured at T(s) = 100 K and corrected by a Debye-Waller analysis, are analyzed to obtain information on the H2-Ag interaction performing close-coupling calculations for a semi-phenomenological potential which reproduces quite well the experimental data. The comparison between the He-metal and the H2-metal potentials indicates that the larger corrugation sampled by H2 as compared to He, originates from the stronger polarizability of H2.
