Paper Abstract

Strong monochromatization of the parametric x-ray emission spectrum is predicted for electrons moving at small angles to the reflecting crystallographic plane of target crystals. The effect can only be realized far from the Bragg-resonance condition and is caused by a long "tail" in the angular parametric-x-ray distribution. In addition, there can be a substantial enhancement of the parametric x-ray yield from grazing-incidence electrons when there is strong asymmetric diffraction (the reflecting crystallographic plane is not parallel to the surface of the crystal). It is shown that this allows one to suppress the influence of photoabsorption on parametric x-ray emission.
