6.4.13.2. Non-absorbing crystal, strong secondary extinction

For this condition, the limiting values of the integrated intensity are [I_{{L}}=(4/5)g^{-1}V^{2/3}], and [I_{{B}}=g^{-1}V^{2/3}.] In this limit, which was also noted by Bacon & Lowde (1948[link]) and by Hamilton (1957[link]), the intensity is proportional only to the mosaic spread and to the surface area of the crystal. No structural information is obtained from the experiment.
