Abstract
Surface light-induced drift (SLID) has been demonstrated to be a highly sensitive tool for studying state-specificity of gas-surface interactions. We compare here the sensitivity of SLID with that of molecular beams. Due to backscattering from roughness facets, SLID can occur even when scattering is completely locally diffusive, providing a significant expansion of the scope of situations in which SLID can show up, compared to the case of a flat surface. Rough surfaces are also a site of enhanced chemical activity, which can affect SLID. We propose a T-shaped cell as a sensitive tool for studying state-specificity of scattering and the chemical reaction process. We discuss prospective directions for further research on SLID.
