Elastic scattering cross section of photons by a nucleus near the particle threshold energy was studied at 120 degrees for Mg, Fe, Zn, As, Cd, Sb and Bi using bremsstrahlung gamma rays. Each element has a gross peak in this energy range. This is consistent with the earlier results reported by T\={o}hei et al. The peak values are 0.5, 1.3, 1.3, 0.6, 1.6, 1.2, and 8 mb, respectively. A systematical relation between the mass number and the energy dependence of the cross section was discussed.
