Trigonometric intensity factors
H. Lipson, J. I. Langford and H.-C. Hu. International Tables for Crystallography (2006). Vol. C, ch. 6.2, pp. 596-598  [ doi:10.1107/97809553602060000601 ]


A summary of the expressions for the intensity of diffraction as recorded by various techniques, including the fundamental constants as well as the trigonometric factors, is provided. Notes on the polarization factor, the angular-velocity factor, the Lorentz factor and special factors in the powder method are included. Some remarks are also made about the integrated reflection power ratio formulae for single-crystal slabs.
