Figure 5
Diffuse-scattering intensity from bixbyite showing selected (hkl) planes of the [(a), (c)] cropped and rebinned experimental data compared with [(b), (d)] RMC refinement values. The region of interest has h and k ranging from 0 to 4 and an l range from 0 to 2 with a grid size of 0.08. A 4 × 4 × 4 supercell is used. The match between experiment and refinement is excellent. The comparison for plane l = 0 with strongest diffuse-scattering features is shown in (a) for the experiment data and (b) for the refinement values, while (c) and (d) show the corresponding data for plane l = 0.5. The RMC refinement captures all of the subtle features of the experimentally obtained pattern with the nuclear Bragg peaks punched out. |
