X-ray atomic scattering factors fX as derived by Cromer & Mann (1968). (a) The change in fX with s or the interplanar distance d. The positions of the indexed vertical bars indicate s = sinθ/λ = 1/(2dhkl) for γ-Fe. (b) A plot showing that fX ∝ Z for constant s. The selected d represent s < 1 (0.05, 0.1, 0.2 and 0.4 Å−1), which represent common band widths in BKD patterns. |
