IFO - A PROGRAM FOR IMAGE-RECONSTRUCTION-TYPE CALCULATION OF ATOMIC DISTRIBUTION-FUNCTIONS FOR DISORDERED MATERIALS

IFO is a newly developed computer program which transforms experimenta l structure factors for disordered materials to atomic distribution fu nctions by employing an image-reconstruction-type technique. The trans formation is carried out through a Monte Carlo search for an atomic di stribution function which is a smooth, i.e. free of termination and ot her spurious ripples, real-space image of a given experimental structu re factor. IFO has been tested on a number of data-sets and its effici ency has been demonstrated. The program is considered to be a useful t ool for controlling and improving the quality of experimental structur e functions for disordered materials.
