For the x-ray diffraction pattern in Figure 15.4 produced with copper K? of wavelength 0.1541 nm, assume that this is some unknown material, but it has been determined that the material is cubic by Laue diffraction.
(a) Prove that the material is BCC.
(b) Determine h, k, and l for each of the lines, but you can ignore the small peak at 35°. This is a K? peak.
(c) Determine the lattice parameter of this material using the (321) peak.
