Abstract
In order to investigate the technical feasibility of X-ray optical devises in the XANES energy region, we used typical carbon compounds with π* molecular orbitals i.e. C60, C70, carbon nanotube and graphite. Their real and imaginary parts of the optical constants were studied. In this study, using XANES observation spectrum data and calculations by the Hartree-Slater method, the atomic-scattering factors of compounds near carbon K-edge region were obtained. It was found that outstanding anomalous dispersions are observed in the near carbon K-edge region; and it was also found that the compounds have peculiar and complicated optical properties due to the chemical-bond structures. Furthermore, based on the obtained results, we designed a metal/graphite normal-incident X-ray multilayer in the region and also considered its application to an X-ray microscopy.
