Determination of the integral characteristics of structural perfection of a real crystal (i.e. Debye-Waller's static factor e-L and coefficient of absorption lids due to diffuse scattering) is especially expedient using the suitably selected wavelengths of the X-ray continuous spectrum by investigation of the thickness I(t), coordinate I(x) as well as amplitude I(W) dependencies of intensities at Lane or Bragg diffraction. Here W is an amplitude of weak ultrasound vibrations excited in a sample for suppression of the Bragg component of reflectivity.
