A Profile Fitting Software Package (CPOWDER) and Its Application in Powder Diffraction Research

CPOWDER, a profile fitting software package for powder diffraction pattern, consisting of several profile fitting programs, a Monte Carlo peak separation program, a background determination program, a plotting program, a simulated pattern generating program and a full width at half maximum fitting program, is developed. The package has been applied in crystal structure determination from powder diffraction data, and determination of particle size and microstrain.
