Investigation into conditions of experimental observation of Borrmann effect in a parametric X-radiation
Spectral-angular characteristics of coherent X-ray radiation of relativistic electrons in a crystal are formulated in the framework of the dynamic theory of X-rays diffraction. Numerical calculations of the radiation angle density are carried out for silicon and germanium single crystal to define...

Digital Library of Periodicals of National Academy of Sciences of Ukraine| Резюме: | Spectral-angular characteristics of coherent X-ray radiation of relativistic electrons in a crystal are formulated in
the framework of the dynamic theory of X-rays diffraction. Numerical calculations of the radiation angle density are
carried out for silicon and germanium single crystal to define the optimal experimental conditions of the anomalously
low photoabsorption (Borrmann effect) observation in the parametric X-radiation (PXR) with Bragg geometry.
The contribution of diffracted transition radiation is investigated depending on semi-infinite single crystal input surface
orientation relatively to definite set of its atomic planes. |
