Top part: calculated structure factors of Si, LaB6 and CeO2 for λ = 1.540598 Å. The structure factors are very different when comparing the crystals with one another. Bottom part: the FWHM extracted from the dynamical theory calculated rocking curves for the same three crystals with D = 100 nm. The FWHMs of the three crystals are the same and follow the curve given by the Scherrer equation. |
