The Le Bail fitting of NIST SRM 660C LaB6 powder pattern measured at 12 keV: experimental data (red circles) and fitted (blue line), with their difference (residual, line below). Insets show fitting profiles of low- and high-angle peaks and IRF. R-factors of refinement are: Rp, 8.51%; Rwp, 11.7%; Rexp, 11.04%; χ2: 1.12. |
