Abstract

An analytical method for precise determination of lattice constants of cubic crystals, from x-ray diffractometric measurements, was formulated. The method minimizes both systematic and random errors and enables the estimation of the uncertainties in the constants. For higher precision, a weighting factor may also be used.

The method was applied to diffractometric data from a Si powder standard reference material and was considered to be highly reliable for precise measurements.
