Abstract:

A rapidly converging radial distribution least squares program RADILS is available for the analysis of x-ray, neutron and electron diffraction data from liquid and amorphous materials. The program automatically generates a radial distribution function, Gr, essentially free from termination effects and determines the empirical background scale and shape, absolute scale factor, bulk density and coordination numbers, disorder parameters and interatomic distances for the first few highly ordered distances in the sample.
