Differential cross-sections for coherent and Compton scattering of 59.5 keV γ-rays at the scattering 55° and 115° by Fe, Ni, Cu, Zn, Zr, Nb, Mo, Ag, Sn, Ta, Au and Pb were measured using a Ge(Li) detector. To measure theoretical coherent and Compton scattering differential cross-sections are extracted by interpolating atomic form factors and incoherent scattering functions corresponding to 2.216 and 4.048 Å-1 photon momentum transfer. The experimental cross-section ratios are compared with predictions of nonrelativistic and relativistic form factors theories.

The total incoherent scattering differential cross-sections of Ti, Cr, Ni, Cu, Zn, Pd, Cd and Ba have been experimentally investigated for 59.54 keV gamma photons in the angular range 30-140° using an improved method. The background correction and detection efficiency are also included in the study. The measured cross-sections have been compared with those estimated on the basis of the non-relativistic Hartree-Fock wave functions.

Differential cross-sections for coherent scattering of 59.5 keV γ-rays for angles ranging from 45° to 125° by Au were measured using a Ge(Li) detector. The results are compared with those of different versions of the form factor theory.
