| Popis | Using Ewald's self-consistent theory of multiple scattering the reflection of the scalar plane wave on an ideal semi-infinite crystal formed by point-like diffraction centres is studied. Exact many-beam dispersion relation and analytical formulae for the reflectivity deduced in our previous papers are analyzed and brought into new forms apt for application in the short--wavelength region. The obtained expression for the reflectivity is effective for the so-called crystal truncation rod scattering as well as the usual Bragg reflection, including the special cases such as total reflection at grazing incidence, Bragg reflection at the Bragg angle Pi/2, and for both coplanar and noncoplanar reflections. |
