Numerical Calculation of Anisotropic Absorption Factors for Lamellar Two‐Phase Structures

X-ray diffraction in a lamellar two-phase material is considered. If the lamellae thicknesses are smallcompared with the penetration depth of the X-rays then the absorption factor depends on the wholepath of incident and reflected beam in both phases. Particularly, it depends on a rotation γ about the diffraction vector s additional to the orientation ( α β ) of this vector with respect to the sample.Numerical calculations of the absorption factor A ( α β γ )have been carried out for different values of lamellae thicknessesD 1 D 2 , absorption coefficientsμ 1 μ 2and lamellae orientations ω ρ with respect to the sample surface.
