Abstract
Differential cross sections for Rayleigh and Compton scattering of 145-keV $\ensuremath{\gamma}$ rays by Cu, Cd, and Pb have been measured from 25\ifmmode^\circ\else\textdegree\fi{} and 80\ifmmode^\circ\else\textdegree\fi{}. The ratio of these cross sections, which can be determined with higher precision than absolute values, is given. The experimental cross sections, which complement earlier results, are compared with the theories of the relativistic and modified form factor and the incoherent scattering function. Agreement exists for the Compton cross section and scattering function theory showing the influence of the binding energy of the electrons. The Rayleigh differential cross sections are found to be lower than the results of the relativistic form-factor theory. Better agreement is found with the modified form-factor theory.
