Abstract

In order to investigate the technical feasibility of X-ray optical devises in the XANES energy region, we used typical carbon compounds with (pi) * 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.
