Hc. Hu, RESPONSE TO MATHIESONS (1998) COMMENT ON A UNIVERSAL TREATMENT OF X-RAY AND NEUTRON-DIFFRACTION IN CRYSTALS - I - THEORY, Acta crystallographica. Section A, Foundations of crystallography, 54, 1998, pp. 251-252
There is an obvious difference between the behaviour of the dependence
of the integrated reflection power ratio on the asymmetric parameter
for plane crystals predicted by the H-D equations on mosaic crystals a
nd that predicted by the theory of Hirsch & Ramachandran on perfect cr
ystals. It is most important to get rid of the surface layer effect of
the crystal sample as much as possible for the verification of such a
difference by experiment. This paper is in response to the comment by
Mathieson [Acta Cryst. (1998), A54, 251].
