摘要：

Two-dimensional anomalous small-angle X-ray scattering (ASAXS) measurements at the K absorption edge of Al have been successfully performed. Contrast change below the absorption edge was detected with the use of a CCD detector. The change of ASAXS intensities near the edge for alumina nanopowder and that for Guinier-Preston zones in an Al-Zn alloy were explained by the anomalous dispersion of Al. The present results showed that two-dimensional SAXS measurements with a dynamic range extended to show Porod's law have been achieved for photon energies of about 1.5 keV with the use of a CCD detector optically coupled with a P43 phosphor plate.
