NaCl-structure can be described with FCC Bravais-lattice and basis {(0, 0, 0); (a/2)}. Show that general form of reciprocal lattice vector is 4π G (hê +kỳ+lễ), a where h, k, l are either (i) integers or (ii) half-integers. Assume that form factors of Na-cations and Cl-anions are f and f.Show that structure factor S(G) is f+ + f for the (i) case and f- fƒ_ for (ii) case.
