Abstract : An analysis was performed on the systematic error functions involved in a determination of the lattice parameters of powder materials using Bragg angles from a standard X-ray diffractometer. Combinations of the pertinent systematic error functions were used to maximize the accuracy of the lattice parameters calculated with a least-squares computer program. (Author)
