Two-dimensional intensity profiles (ω:ϕ maps) of a three-beam diffraction for (a) σ and (b) π polarizations. Primary wave EP from reflection 006 (reflection A). Secondary wave ES from reflections 113 and (B and C reflections). Crystal: GaSb (001). Wavelength: 1.4370 Å. Beam divergences: 9" (vertical) and 23.8" (horizontal). Mesh resolution: (a) 0.0032° and (b) 0.0016°. |
