Bragg's Law is a necessary but not sufficient condition for diffraction by real crystals. Determine the Miller indices for the first five lowest reflections that are present for a single atom in BCC and FCC unit cells. (Problem from P.132 problem 1.II.4.)

Step 1
For a single atom in a crystal, the reflections that are present are determined by the lattice structure and the arrangement of atoms within the unit cell. For a BCC (body-centered cubic) unit cell, the Miller indices for the first five lowest reflections can be Show more…
