Incoherent scattering of 59.54 keV gamma rays by selected elements in the atomic region 29⩽Z⩽74

Incoherent scattering cross-sections for 11 moderate to high atomic number elements have been experimentally determined using 59.54 keV gamma rays emitted by the radionuclide 241Am. Measurements were performed using a standard back-scattering geometry set up to obtain scattering angles of 145°, 154° and 165°. Resulting photon momentum transfers were in the range 4.58⩽x⩽4.76 Å−1. High purity (better than 99.9%) foils of Cu, Zn, Zr, Nb, Mo, Ag,...
