Abstract
X-ray interferometer moire patterns have been used to completely determine the Burgers vectors of several dislocations. Because x-ray moire patterns could be obtained under controlled conditions and with many different Bragg reflections it was possible to determine not only the magnitude direction and sense of the Burgers vectors but also to elucidate some hitherto unnoticed geometrical problems involved in the interpretation of x-ray interferometer moire patterns.
