The angles between the Kikuchi line pairs can be measured accurately. Some indexed Kikuchi lines for a 110 bcc diffraction pattern when the crystal is oriented precisely along the 110 zone axis. If that is the case, then the lattice is most probably fcc. The practice of indexing single crystal diffraction patterns is explained.
For a cubic structure, $$ d = \frac)$ imposes the condition that h,k,l muat be all odd or all even. The Bragg's Law gives the relation $ \lambda = 2d sin(\theta) $. Here you will find options to view and activate subscriptions, manage institutional settings and access options, access usage statistics, and more.If the lattice structure is cubic, one can decide whether it is bcc, fcc or simple cubic from the diffraction data.
