Farhan-a qualitative and quantitative PC program for x-ray powder diffraction

摘要

Farhan is a PC interactive, graphically oriented search-match-identification-quantification computer program for x-ray powder diffraction, which uses a variable intensity-error widow (IEW). Both the intensity scale factor and the IEW for each standard phase are estimated by a simple iterative procedure. A new tunable combined figure-of-merit (agreement function) is suggested for estimating the goodness-of-fit of matches.
