A Study of the Diffraction of Thermally Scattered Radiation in a Pyrolytic Graphite Crystal by Means of X-Ray Film and Mössbauer Diffraction

Abstract
A defect line in the 002 diffuse spot of MoKα X-rays from a pyrolytic graphite crystal was observed in the diffraction pattern on an X-ray film. On the other hand, a dip in the inelastic intensity profile in the 002 Bragg reflection from the same crystal was observed also by means of Mössbauer γ-ray diffraction using 14.4 keV γ-rays and a position-sensitive detector. The correspondence between the defect line and the dip was ascertained using the two methods mentioned above.
