Bremsstrahlung,Cerenkovstrahlung und Übergangsstrahlung in einer dünnen Schicht

We present a formula for the coherent emission of Bremsstrahlung, Cerenkov radiation and transition radiation of a single electron traversing a thin foil at an oblique angle of incidence and changing its velocity (direction or amount) inside the foil. As an example we consider the bombardment of silicon foils with 50 keV electrons. The statistical scattering of the electrons inside the foil is taken into account by means of a measured scattering pattern.
