| Abstract: | Green's function of the wave equation for a perfect crystal is obtained by means of Fourier integration. Using Green's formulae, the expression of X-ray transmission wave field, D0 Dh, have been derived. With incident spherical and plane wave, Dh,D0 value are found and compared with previous results of other authors. Relationship between thickness of the sample and D0, Dh is discussed. |
