Abstract
An analytical expression is obtained for the rocking curve of a double-crystal spectrometer, which does not require restrictions on the absorption cross section dependency on the wavelength. A modeled rocking curve (instrumental line) for the Bragg–Bragg spectrometric scheme is calculated using the example of an InSb crystal in the region of weak dependency between the absorption cross section and the wavelength and in the region of wavelengths close to the absorption resonance.
