Abstract
To study the mosaic structure of crystals, the technique of Lambot et al. (8) was extended in such a way that a point-to-point correspondency was established between specimen and diffraction pattern. The resolution of angle and position are discussed in detail. In addition, the instrumental errors in obtaining the angular range of reflection are discussed. Two instruments were constructed; one was designed for transmission experiments (Laue case) and the other for reflection experiments (Bragg case). The linear resolution was about 20 μ in the most favorable case. The angular resolution of misorientation about the vertical axis was a few seconds of arc, and that about the horizontal axis in the net plane was ca. 1 minute. (The net plane was set in a vertical plane.) The textures of quartz, NaClO 3, KCl and Ge were studied by this technique. It was found that Cottrell's assumption on dislocations was satisfied in some cases of fairly good KCl crystals, but not in the other cases. Hirsch's assumption was satisfied in quartz and Ge specimens but not in the other specimens.
