摘要：

Profile and Bragg R values are discussed with respect to different versions of the Rietveld program. The R values calculated from an exemplary neutron diffraction pattern are compared. Results obtained by a modified treatment of background and by a simplified method to decompose an observed pattern into Bragg intensities are presented.
