Abstract
The results of the measurement of the Ni Kalpha2 spectral-line peak wi th a double-crystal.spectrometer with thick perfect silicon crystals i n the dispersive arrangement (440 sym., +440(3) sym.) were published s ome time ago. A sharp anomaly was found in the measured rocking curve when the second crystal was adjusted for coplanar three-beam Bragg 440 (3) diffraction. In this paper, the experimental curves are compared w ith the precise calculation based on the dynamical theory of X-ray dif fraction.
