Polarization correction for crystal-monochromatized X-radiation

Abstract

The polarization correction for diffraction of a crystal-monochromatized X-ray beam is derived. Suitable expressions for different experimental methods are also given. The polarization correction is first tabulated in parts so that the appropriate correction for any wavelength and monochromator crystal can be determined. Another table lists selected values of the polarization correction, in a final form, for different wavelength X-radiations reflected from (1011) planes of a quartz monochromator. The maximum correction for Ag Kα is a little more than 1%, whereas for Cr Kα the maximum correction is 34%.
