Only the Bragg case for thick crystals will be considered here. The asymptotic values of A, B, and C are ,
, and
, respectively, so that
For BCx small, the integrated intensity,
, is given by
For BCx large,
It can be shown that the parameter g (which has no relation to the parameter g used to describe the mosaic-block distribution) used by Zachariasen (1945
) in discussing this case is equal to −μ/2NCF. Hence, on his y scale,
The value he obtained is IB = 8/3[1 − 2|g|], while Sabine & Blair (1992
) found IB = 8/3[1 − 2.36|g|].
