Problem: Integrated Scattering Intensity

  Assume that in a scattering experiment the amplitude of scattered radiation is

equation1206

where tex2html_wrap_inline5563 is the scattering wavevector and tex2html_wrap_inline5545 is the position of atom n. The intensity is given by tex2html_wrap_inline5569 . Show that the integrated intensity,

equation1212

is independent of the atomic positions!
