Solutions of the Klein-Gordon and Dirac equation for a charged particle in the field of an electromagnetic plane wave in a medium with a constant refractive index n are discussed. Generally, for n2 < 1, spontaneous pair creation from the vacuum, and for n2 > 1, energy bands are observed. The interplay of Compton and Cherenkov scattering is discussed....</1,>
