Abstract
Formula for calculating the atomic scattering factor for spherical x-ray waves is derived and used to solve the near field effects problem in X-ray Fluorescence Holography theory. A rigorous formalism to calculate the X-ray fluorescence hologram for given atomic distributions is then given so that quantitative structural information can be derived from XFH measurements.
