Scheme of X-ray symmetrical two-wave dynamical diffraction, i.e. the reflecting lattice planes RP are perpendicular to the entrance surface of the crystal. Shown are , the wavevector of the incident beam; θi, the angle between the incident wave wavevector and the reflecting planes; h, the diffraction vector; Oxz, the coordinate system in the diffraction plane. Diffracted and transmitted beams emerge from the exit surface. |
