title: Phase-dependent polarization aspects of three-wave X-ray diffraction: an iterative Born approximation.
abstract: The iterative Born approximation is derived for three-wave dynamical X-ray diffraction. Dependence of the three-wave diffraction profiles of the diffracted wave on the polarization state of a linearly polarized incident wave is theoretically and experimentally investigated. General conditions of the phase sensitivity as well as the asymmetry of diffraction profiles are obtained from this approximation and compared with direct dynamical calculations. Reasonable qualitative agreement between the results obtained from this iterative approach and the exact dynamical calculation is shown. A new feature of reversing asymmetry of an intensity profile with respect to phase change is theoretically predicted.
