Abstract
It is well known that transitions such as Is-to-π* transitions possess an angular dependence. In particular, the transition is optically forbidden at the normal-incidence angle because the electric vector of X-ray is perpendicular to the π* molecular orbital. This means that compounds possessing π* molecular orbitals, such as graphite, become transparent at the normal-incidence angle. Using this optical property, we propose a design for a metal/graphite normal-incidence X-ray multilayer device. It is expected that the designed mirror will have a reflectance of 35% in the XANES region of carbon. Finally, we consider an application of the mirror to biological X-ray microscopy.
