It is shown that in case of Bragg geometry it is necessary to use dynamical approach for PXR consideration. The comparison of the theory and experiment is carried out.Latex, 10 pages with 5 eps figureHigh Energy Physics - PhenomenologyTheoretical interpretation of the experiments on Parametric X-ray radiation in case of backward diffractiontext
