Differential cross sections for coherent scattering of 59.5 keV γ-rays 55° (scattering) by Ti, Fe, Ni, Cu, Zn, Zr, Nb, Mo, Ag, Sn, Ta, Au and Pb were measured using a Ge(Li) detector. From these accurately measured cross sections atomic form factors are extracted corresponding to 2.216 Å-1 photon momentum transfer. The results are compared with predictions of form-factor theories, and the appropriateness of these theories is discussed.
