The main features of dissociative scattering of H-2(0) and H-2(+) from Pd can be explained with this model. For the H-2(+) --> Al (1 1 0) system we consider, beside the electron capture processes For a description of the molecular survival probability as a function of translational energy, an additional process of dissociation: collision induced excitation of the triplet state.
