The authors report high resolution state resolved measurements of the translational inelasticity of HCl (v=0→0,J=0→4) colliding with a Au(111) surface at near normal incidence in the energy range of 0.28-1.27 eV. The translational inelasticity is large and indistinguishable from previous measurements for the HCl (v=2→2,J=1→5) channel. They discuss these observations in terms of an impulse approximation as well as the possible role of translational excitation of electron-hole pairs in the solid.
