Abstract
Using the radioactive gamma ray source 141Ce (Er = 145 keV) and Ge(Li) detector (FWHM = 2.21keV at 1.33 MeV), we have measured the cross sectipn of photon coherent scattering from Al, Fe, Cu and Pb over the range of momentum transfer x=1.2-5.0 ?-1. The theory of form-factor approximation resulting from relativistic Hartree-Fock (RHF) atomic model is found to be adequate in explaining the experimental results.
