Spectral Observation of Surface-Induced Van der Waals Attraction on Atomic Vapour

Red frequency shift and line asymmetry have been observed in selective reflection spectroscopy at a dielectric/Cs-vapour interface, which have been attributed to surface-induced Van der Waals attraction. This opens the way to studying surface interaction on low-lying, short-lived, excited states.
