ON THE INTENSITY OF KOSSEL REFLECTIONS

The line intensity of Kossel reflections of various single crystals (A1, A2, B3, B4 and C16 type of structure) has been studied experimentally as well as theoretically. In contrast to earlier results high excess intensity of experimental Kossel lines can be explained solely by dynamical diffraction without an additional consideration of real structure effects. It has been shown that the different maxima of intensities of Kossel lines found above all result from the different line width, depending strongly on the X-ray wavelength used (lambda = 0.47 - 8.34 angstrom): Sole convolution of the theoretical profiles partly transforms the differences in the line width into variation of height.
