Figure 2
Schematic of the relation between Ko, the wavevector of the incident X-rays, and n001, the (001) surface normal, or [{{\bf{n}}_{0\bar11}}], the [\left({0\bar11}\right)] surface normal. Angles [({\pi/2})-{{\omega}}] and [{{\omega}}-({\pi/4})] correspond to direction cosines γo of Ko to n001 and [{{\bf{n}}_{0\bar11}}], respectively.
