Specular reflectivity of the α-Al2O3 (012)–water interface. (a) Individual CCD images at L = 1.05 and 1.95, showing a splitting at L = 1.05 due to a surface that is miscut by 0.14° with respect to the crystallographic (012) plane. Also shown are one-dimensional integrations of the individual spectra along X and Y, as described in Fig. 4[link]. (b) Specular reflectivity of the surface in water measured at the 11-ID-D beamline (red triangles). The solid line is a best-fit calculation. (c) The same data as in (b) but shown as a projection of the full three-dimensional CCD data set onto the Qz–Q// plane (note that the aspect ratio is distorted with a Q// range that is greatly exaggerated for clarity). Two projections are shown along the X and Y axes of the CCD images. Note that the splitting of the rod along the Y direction is not seen in the X projection.
