Observation of direct vibrational excitation in gas-surface collisions of CO with Au(111): a new model system for surface dynamics
Abstract
We report vibrational excitation of CO from its ground (v = 0) to first excited (v = 1) vibrational state in collision with Au(111) at an incidence energy of translation of EI = 0.45 eV. Unlike past work, we can exclude an excitation mechanism involving temporary
