The elastic differential scattering cross section of 9.0 MeV photons on 238U has been measured at θ = 1.2°, 1.5°, 25°, 35°, 45°, 60°, 75°, 90°, 120° and 140°. The results show good agreement with theoretical calculations at θ = 1.2° and 1.5°. At 25°, 35°, 45° and 60° a deviation from theory by a factor ≈1.8 was observed. This deviation decreased with increasing angle. Those results, together with data at E ≈ 7.9 MeV in U, were compared with similar data in 181Ta and evidence for the contribution of Coulomb corrections to Delbrück scattering was obtained.
