We have measured state-to-state scattering in the H-2-Cu(100) and H-2-Cu(110) systems for H-2 initially prepared in the v=1,J=1 state, for several final (v,J) states. We observe survival in the initial state (v=1,J=1), rotational excitation within v=1 (into v=1,J=3), and rotational excitation plus vibrational relaxation into final states (v=0,J=5) and (v=0,J=7). For each of these final states, we measure the branching fraction (relative to the incident v=1,J=1 flux) and the mean final translational energy. In addition, for rotational excitation from J=1 to 3, the dependence on initial translational energy and surface temperature is measured within v=1 and compared with results within v=0. Our results are compared with published state-resolved associative desorption results, similar scattering experiments, and recent theoretical calculations. (C) 2001 American Institute of Physics.
