Abstract
A new technique for realization of diffraction of a widely divergent beam of characteristic X-ray radiation in crystals is developed. It is shown that the X-ray diffraction image is a set of hyperbolas, which are formed by radiation diffracted from certain points of the crystal surface (active points). The active points are also located along hyperbolas and to every point of the diffraction image corresponds an active point on the crystal surface. The diffraction pattern is a magnified image of the distribution of active points. The diffraction magnification has been determined experimentally and it was shown to coincide to high accuracy with the calculated value. A method is proposed for detection of structurally distorted local domains and determination of their sizes.
