Examples of reflection profiles and Gaussian fits: (a) The (−5 −3 −51) reflection was broadened by Lorentz and beam effects and the measured FWHM value of φR was 0.055°. Deconvolution with (5) resulted in a mosaicity of 0.007°. (b) The (−9 −13 −16) reflection lies along the vertical axis. The measured FWHM value of φR was 0.0173° and the deconvoluted FWHM mosaicity was 0.0130°. Definitions for FWHM and FWQM are indicated. The positions of these reflections on the detector are indicated with arrows in Fig. 5. |
