The temporary trapping of conduction electrons in surface states may result in singularities in the scattering probability with respect to the incident direction, so-called conduction electron surface resonances, if the conservation of momentum can be satisfied by a suitable surface structure. We present evidence for the observation of these resonances by means of transverse electron focusing on a Bi single crystal with an artificially produced grating on the surface.
