Abstract
The ratio method, designed originally for powder materials, is modified for single crystals. A relatively simple goniometer with photographic registration is used. Discussion of random and systematic errors shows that an accuracyΔa/a = 10−4, or better, can be achieved. An application for single crystals of Fe and Fe-Si alloys is demonstrated. For pure iron the valuea= = (2·8664±00001)×10−10 m is found.
