Differential cross-sections for incoherent and coherent scattering of 59.54 keV photons were measured for Cu and Zn targets at scattering angles of 40-135degrees in a reflection geometry setup with a graded shielding arrangement. The ratio of these cross-sections, which can be determined with higher precision than absolute values, is given. A method was used to determine differential incoherent and coherent scattering cross-sections of elements. This method is based on simultaneous measurement of fluorescence radiation and scattered radiation, thus avoiding problems with measuring source strength and source-to-detector solid angle. The measurements were performed using a point source of Am-241 radioisotope and an Si(Li) detector. The experimental results, which complement earlier results, were compared with the theories of incoherent scattering function and form factor. Copyright (C) 2004 John Wiley Sons, Ltd.
