Theory of the electron-surface-polariton interaction. Application to electron-transmission experiments

The interaction of a non-relativistic charged particle with a surface polariton in a crystal slab is formulated quantum mechanically and applied to calculate probabilities of surface-polariton emission. The electron energy-loss function relevant for electron-transmission experiments is calculated in the Born approximation. Retardation corrections to the electron spectrum are discussed for a dielectric and a metallic slab at normal electron incidence and for single- and multiple-scattering processes.
