Extinction coefficients for pure and doped single crystals of potassium chloride have been measured with the use of polarized X‐rays and subsequent analysis in terms of Zachariasen's theory of X‐ray diffraction from real crystals. The sizes of the mosaic domains and the angles of misorientation between them have been determined from the extinction coefficients corresponding to copper and cobalt radiations. It has been observed that with increase in doping the sizes of the domains diminish and the misorientation between them increases.
