(a) Specular reflectance map of quartz (y cut) for the measured θi and photon energy range E in the (001) direction. The white region marks the area not measurable owing to the carbon edge. (b), (c) Comparison of the measured reflections for the crystal directions (100) and (001) at a fixed angle of incidence θi around the (b) Si L2,3 and (c) O K absorption edges. The lower maps in (b) and (c) show the respective anisotropy maps. |
