2) A thin crystal of the metal oxide with a tetragonal crystal structure and lattice parameters a = 4.05 Å and c = 2.517 Å is tilted so that a 200 kV electron beam travels along the [001] zone axis. Create a schematic diagram of zero order Laue zone (ZOLZ) diffraction pattern for a crystals of thickness: a) 75 Å b) 400 Å You should assume there are no forbidden reflections and that the diffraction intensity drops to zero when the excitation error, s, exceeds the first minimum of the relrod. You should show the approximate number of beams in the ZOLZ circle. (10)
