Basic equations of dynamical diffraction theory for elastically deformed single crystals with defects are obtained in the momentum space. The solutions for strong Bragg and diffuse waves are obtained and investigated in the two‐beam approximation. The corrections to Fourier components of the polarizability describing the influence of the diffuse and „quasi‐diffuse” scattering on the attenuation of the amplitudes of strong Bragg waves are obtained in a general form.
