Black diffraction lines and black-and-white lines were observed across the 220 thermal diffuse spot on X-ray film photographs of perfect germanium crystals using monochromatized synchrotron radiations. The diffraction line profiles were observed by means of two-crystal and triple-crystal diffractometries. A good agreement between the experimental diffraction line profile and the theoretical calculation based on the dynamical diffraction theory obtained leads to the conclusion that the cause of the line can be attributed to the anomalous transmission of the thermally scattered X-rays in the absorbing perfect crystal.
