In order to determine short‐range order in a solid solution from diffuse X‐ray or neutron diffraction experiments the separation of atomic size effects from the experimental data is a crucial problem. It is demonstrated by a model calculation that a clear improvement of the separation method proposed by Borie & Sparks is obtained if the range of measurement is extended to include the first Brillouin zone.
