Zc. Xu et al., BRAGG REFLECTION AND TRANSMISSION OF X-RAYS INDUCED BY THE IMAGINARY PART OF THE ATOMIC SCATTERING FACTOR, Journal of physics. Condensed matter, 7(42), 1995, pp. 8089-8098
Formulae for x-ray dynamical Bragg diffraction are derived for a plane
-parallel crystal with arbitrary thickness. These formulae are applica
ble even when the contribution of the real part of the atomic scatteri
ng factors to the structure factor vanishes. Based on these formulae,
dynamical Bragg reflection and transmission induced only by the imagin
ary part of the atomic scattering factor are studied in detail.
