Figure 1
Part (a) shows the Ewald construction for the simple multiple-scattering case with scattering vectors G and L simultaneously intersecting the sphere [the reciprocal-lattice vectors are in red and the beam vectors are in green for (a) to (d)]. Part (b) shows the Ewald construction extended for diffuse multiple scattering. The reciprocal-space origin changes with the incident angle (we are now assuming multiple incident beams). Consequently, the positions at which the reciprocal-lattice vectors intersect the sphere are changed, producing lines. Parts (c) and (d) provide a simplified view of (b) at two different projections. v0 and vn refer to the resulting vectors connecting the new origins to the surface of the sphere for a range of incident-beam vectors 0 to n. |
