Notes:
A white (defect) line which appears as a dip in intensity distribution was clearly observed in the 200 diffuse scattering from a Cu-Al disordered crystal at room temperature in the Bragg geometry by using both photographic and counter methods. The line is caused by the extinction effect on the 200 Bragg reflection, subsequent to the diffuse scattering, in a process similar to the case of mosaic crystals. The diffuse scattering is caused by the static displacement as well as the thermal motion of atoms. The observed contrast of the line is quantitatively in fair agreement with that calculated.
