Experiments on Rayleigh Scattering of 145 keV and 317 keV Photons

Abstract
Elastic differential cross sections for scattering of photons with 145 keV and 317 keV were measured for Pb, W, Sn, Cd, Ag, Mo and Cu for angles from 5° to 40°. For measuring the strong energy dependence of the cross section at small angles, a well collimated beam (±0,5°) and a small detecting solid angle were used. For the energies and angles studied, agreement between experiment and form factor calculations is found. The results are compared with recent measurements of other authors, which found disagreement with form factor calculations
