Comment on the use of 224 reflections with g . b = 0 for determining stacking faults widths

Abstract

Abstract The properties of weak-beam images of dissociated dislocations obtained in 224 reflections with g . b = 0 have been investigated. Calculations and contrast experiments show that this type of reflection is, in general, less suitable for determining stacking fault widths than the corresponding 220 reflection with g . b = 2.
