    Abstract

    In x-ray diffraction experiments the parameters of interest are the position of the peak, fullwidth at half maximum intensity, integral width, peak intensity and integrated intensity. The profile fitting technique is used to derive accurate values of these parameters. In13; this report the results obtained by fitting four analytical functions (Gaussian, Lorentzian, Pearson VII and split Pearson VII) by the simplex method to the observed x-ray diffraction data from overlapping peaks13; are presented.
