Figure 5
Comparison of (a) reflectance and (b) FWHM of YB66(400) and beryl(1010) in the 1–2 keV region from single-crystal rocking curves measured on the KMC line at BESSY. The open triangles correspond to the Mg Kα data and the open circles were obtained from an energy scan at fixed Bragg angle at 1.4 keV. The data have not been corrected for divergence of the incident light. |
