Abstract : The production of spurious lines of intensity in high energy electron diffraction patterns by double diffraction between a strong Bragg reflection and a plane of diffuse intensity was demonstrated in a Ti-Nb alloy containing the omega phase. The conclusion that (111) planes of diffuse intensity passing through the reciprocal space origin are absent was shown to be consistent with the presence of <111> rows of omega particles suspended in a b.c.c. matrix.
