Calculate the structure factor for monoatomic crystals in FCC and diamond lattice symmetries. Discuss the extinction rules for diffraction spots parametrized by the reciprocal lattice indices (h, k.l). Compare the differencies in the rules for the two crystals. What is the connection of the result to the lattice planes?

1. A powder diffraction pattern is recorded on a sample of an unknown elemental substance known to have cubic symmetry. Cu K-alpha x-rays (wavelength of 0.154 nm) are used and the θ values of the first 7 peaks are 14.22°, 23.64°, 28.05°, 34.55°, 38.17°, 43.99° and 47.45°. (a) What are the lengths of the reciprocal lattice vectors (or change in x-ray wave-vector) corresponding to these Bragg angles? (b) For a cubic structure, these lengths should be equal to (2*Pi/a)(h 2...
