A polycrystalline powder can be represented in reciprocal space as a set of nested spherical shells positioned with their centers at the origin1(Figure 9.1). These shells arise from the reciprocal lattice points from the myriad (e.g. ≈109 mm−3 for 1 μm crystallites) of small crystals, ideally with r...
