Elastic and Raman scattering of 8.5 to 11.4 MeV ..gamma..-ray photons are investigated between charge numbers of 73 and 92. The experimental elastic scattering cross sections show large deviations from calculations based on available giant dipole resonance photoabsorption cross sections and on lowest order Delbrueck amplitudes. The elastic differential cross sections measured at Z = 83 and 90 confirm the indications of a Coulomb correction effect in Delbrueck scattering previously obtained for Z = 92 only. By a systematic analysis, quantitative information on the Coulomb correction effect in Delbrueck scattering and on scaling factors for the giant dipole resonance photoabsorption cross sections is obtained.
