Figure 5
CeO2 unit-cell parameters at 25°C at several displacement locations with corrections from the internal reference material and equation (1). `Original' used integration parameters from an external CeO2 XRD scan at the start of the experiment, `Corrected–Internal RM' used integration parameters from the internal SRM 674b CeO2, and `Corrected–Eq. 1' used equation (1) during the Rietveld refinement step. Both corrections were accurate, but the internal RM correction had higher precision than equation (1). |
