Footnotes

1 The reciprocal lattice is a commonly used construct in solid-state physics, but with a different normalization: [{\bf{a}} \cdot {{\bf{a}}^{\bf{*}}} = 2\pi ].
2 For practical reasons, plots of the Ewald `sphere' are circular cuts through the sphere and the corresponding slice of reciprocal space.
3 Strictly speaking, the term crystallite size here refers to the dimension of a coherently scattering domain. Only in a perfect crystal is this the grain size.
