The correction of measured integrated Bragg intensities for anisotropic thermal diffuse scattering

The correction of measured integrated Bragg intensities for first-order thermal diffuse scattering was considered in an earlier paper [Cooper & Rouse, Acta Cryst. (1968). A24, 405] using an approximate method, valid for pseudo-isotropic materials. A method is now derived for the evaluation of the correction for a crystal of any symmetry, allowing for the contributions from first- and second-order scattering for X-rays or neutrons. Allowance for the effects of experimental resolution is also considered.
