A universal computation method for two-beam dynamical X-ray diffraction

X. Huang and M. Dudley

Abstract: A general-purpose method that includes nearly all possible two-beam diffraction mechanisms is presented for calculating diffracted and specularly reflected X-ray intensities from single crystals. Based on this method, it is demonstrated that a small universal computational routine can be developed to accurately treat two-beam diffraction for any scattering geometry.

Keywords: dynamical theory; dispersion equation; computation procedure.
