Figure 14
DuMond diagrams corresponding to the 12.66 keV case. (a) The full DuMond diagram and including harmonics up to λ/7. (b) Magnified (by a factor of 10⁴) version in the vicinity of the fundamental (λ). (c) Magnified (by a factor of 10⁴) version in the vicinity of the λ/3 harmonic. The effects of the Darwin width and the beam divergence are incorporated and the intersection of the associated lightly shaded regions, represented by the darkly shaded parallelogram, will be the focus of our attention. The effect of refraction is also included in the diagrams. In (a) the λ/2 and λ/6 harmonics are shown in grey because they relate to `forbidden' Bragg reflections (222 and 666, respectively). In (c) we have included an insert graph with an enlarged view for clarity. Further details are provided in the text.
