Line profile functions for a powder of (a) spherical crystallites and (b) cubic crystallites: (111) blue; (200) orange; (220) green. The diameter of the sphere is chosen to have the same volume as the cube: Dc = 10 and Ds = 12.4. The abscissa is . Units are coherent, i.e. if Dc, Ds are in nm or Å, x is in nm−1 or Å−1. |
