(a) Rietveld refinements of the NIST CeO2 powder data obtained in the standard scan mode. The inset shows an expanded view of the high-angle data. The powder was filled into a 0.2 mm diameter Lindeman glass capillary. (b) Rietveld refinements of the NIST CeO2 powder data obtained in the single-step scan mode. The markers and line show the measured (Iobs.) and calculated (Icalc.) data, respectively. The intensity difference curves (Iobs. − Icalc.) are offset for clarity. All data were measured using an X-ray energy of 35 keV. |
