Rietveld refinement of a NIST LaB6 SRM 660c PXRD pattern, measured with a 20 keV X-ray beam, performed with Fullprof using the pseudo-Voigt line shape. Before the refinement, the data were corrected by Lorentz and polarization factors, flat-detector corrections and interaction volume of X-rays with a capillary. The background was subtracted by fitting a Chebychev polynomial (16 coefficients). |
