Sample broadening Bragg reflection

Figure 3. (A) Real and (B) reciprocal space representations of a single crystal with three Bragg planes noted in (A) and their corresponding Bragg conditions shown in (B). Note that the momentum transfer for each Bragg peak in (B) has an orientation that is perpendicular to the Bragg planes noted in (A). A schematic powder diffraction pattern of the structure shown in (A) is shown in (C) with each reflection identified. A reciprocal space description of a powdered sample is shown in (D), in which each Bragg spot is broadened into Bragg rings.
