Figure 3
Calculated transmitted and diffracted rocking curves for the GaAs 200 reflection with a crystal thickness of 133 µm and the temperature factor B = 0.64 A2 for (a) 10.3645 keV, (b) 10.5020 keV, (c) 11.3430 keV and (d) 11.8050 keV. (a), (b), (c) and (d) correspond to the resonant scattering conditions A, B, C and D, respectively, in Fig. 1. Dotted lines correspond to the intensities given by the mean absorption coefficient () and broken lines correspond to the averaged values for the rocking curves with the Pendellösung beat. The inset circle denotes the diffraction condition in the (u, v) plane. |
