Abstract

Atoms in crystalline lattice have been identified around a certain fluorescent atom by x-ray fluorescence holography (XFH) under resonant x-ray scattering phenomena. With this method named "complex x-ray holography (CXH)," the twin image problem can be solved by determining complete phases of scattering x rays. Very weak signals of CXH less than 0.01% of fluorescent intensities were successfully observed by cooling a sample, and adopting a fast x-ray detecting system combined of a cylindrical focusing graphite analyzer and a Si PIN photodiode. Isolated As atomic images were successfully reconstructed from experimental complex x-ray holograms of GaAs around the As K absorption edge.
