Abstract
Experimental measurements of the inscribed radius, the outer radius, and the character of extended nodes have been compared with the theoretical predictions of the recent work by Brown, Siems, and Jo/ssang et al. The most comprehensive comparison has been made for the two former theories, which have been found to predict accurately the observed node parameters. Within the range γ/Gb −2 the node method appears to be an excellent means of determining the stacking‐fault energy.
