Abstract: By coordinates transformation and calculation with the Least Square method, we can determine the parameters of the Newman equation which represents the back reflection pseudo-Kossel curve. From the parameters, the planar spacing d of the corresponding lattice planes can be calculated. In our experiment, the d {533} of a single crystal silicon is measured. The accuracy of measurement is about 8×10-6nm. The experimental procedures and the principal sources of error are also discussed.
