Abstract

AbstractThe theory of Huang scattering of point defects in hexagonal crystals is treated. The concept of “elementary defects” which is based on group theoretical methods is introduced. From this point of view, point defects in hexagonal crystals can be understood as unique superpositions of three types of incoherent elementary scattering defects. These elementary defects reflect characteristical defect symmetries. This concept yields a simple analytical expression for the Huang intensity in the case of arbitrary scattering vectors. The derived intensity function may be a useful tool for the investiga‐ tion of defect structures in h.c.p. metals by Huang scattering measurements.
