Figure 5
CeO2 pseudo-Voigt peak width versus diffraction angle for four different energies, shown as a function of cos2 2θ and 2θ. The circles are data, and the solid lines are fits to a quadratic in cos2 2θ, as described by Chernyshov et al. (2021). The dotted lines in the lower panel represent the calculated contribution from the bandpass of the monochromator, and the nearly horizontal line that of the pixel size, to the resolution function. These two terms are dominant over the effect of detector transparency, too small to be fitted accurately. |
