Figure 5
Calculated intensity curves for a bent Si 111 crystal, energy = 20 keV, crystal thickness = 300 µm, q0 = 4500 mm, the remaining parameters are the same as for Fig. 4. (a) Intensity at the symmetry centre versus q showing the intensity maximum at q = 820 mm, (b) intensity profiles for q = 820 mm (solid curve) and for q = q0/4 = 1125 mm (dashed curve). Note that α = 0.73. |
