Parametric X-radiation (PXR) of a relativistic electron travelling through a monocrystalline plate is examined in the Laue scattering geometry under the assumption of asymmetric and symmetric reflections of the particle field with respect to a target surface. The formulas of the kinematic and dynamic approaches to PXR characterization are analyzed and compared. The results of the experiment on relativistic electron PXR implemented at the Mainz microtron are interpreted using an expression derived for its angular distribution. It has been revealed for the first time that the dynamic effect of anomalous photoabsorption (the Bormann effect) of PXR has taken place in this experiment.
