The variation of the interference function, , between (500) and (600) Bragg reflections for the hexagonal unit cell, a = b = 281, c = 165 Å. The is calculated using equation (12b), assuming that , where d_{100} is the interplanar distance along the (100) direction of the crystal lattice. (1) = 0.0, (2) = 0.002, (3) = 0.005, (4) = 0.008.
