摘要：

A model calculation for the dissociative scattering of hydrogen molecules from metal surfaces is carried out with the aid of the Hubbard model for the metal substrate. The Coulomb interaction between electrons in the substrate is taken account of within the single-site approximation in calculating the probability distribution of the dissociative scattering. It is shown that the probability for the dissociative scattering of hydrogen molecules increases as the magnitude of the Coulomb interaction between electrons in the metal substrate is increased.
