N2 - Abstract: We discuss the methodological questions of measuring unit cell parameters of small crystals in Bond’s scheme on a commercial diffractometer equipped with a three-circle goniometer and a 2D detector. The effect of the sample eccentricity on the positions of X-ray diffraction reflections during rotation about φ and ω axes is examined. The approach is developed to eliminate the effect of the sample eccentricity related to rotation about the φ axis by positioning one of the crystallographic directions along the ω axis. The unit cell parameters are measured for the reference Si and Ge single crystals used in this work with relative error Δa/a no worse than 6.5·10–5.
