Figure 8
The calculated scattering captured by a linear detector with no axial width from a single Si crystallite fixed at one orientation, which gives an indication of how the powder diffraction pattern is created. This pattern was one that gave the highest number of reflections, chosen from a randomly orientated set of ten crystallites. Typically the number can be anywhere between 0 and 12; the latter is the full complement of unique peak positions out of the 246 reflections. The reflections that were captured in this angular range appear in the right-hand lower quadrant and represent the ranges 0 (or π − 2θ) < Ω < 2θ (or π/2), −π/2 < X < π/2 and for 0 < 2θ < π (provided 2θ < 4θB). |
