Figure 3
Exact (solid lines) and approximated (dashed lines) solutions of the dispersion equation. Model: incident angle = 3°, wavelength λ = 0.154 nm. Single Si crystal, surface orientation (001), scattering crystal planes series {220}, miscut angle ψ = 2°. (a) Large scale, (b) near the Laue point, (c) close to the Bragg condition. |
