Description
Elastic scattering of photons from solid samples of Pb, Pt, and W was measured in order to investigate the limits within which scattering experiments can be described as being due to free atoms. The experiments were performed with photons of 22.1 keV from an x-ray tube and from an 241Am (59.54 keV) γ source, providing a momentum transfer ranging from x=0.1 to 2.0 A-1. It is shown that the low-momentum-transfer limit for the free-atom approximation will depend on the scatterer, temperature, geometrical resolution, and on the accuracy of the experiment
