摘要：

Average elastic photon scattering cross sections were measured for Bi209, Pb208, Pb207, Pb206, Tl and Hg at excitation energies between 4.5 MeV and the neutron emission threshold, with an energy resolution in the range between 50 and 150 keV. This resolution was sufficient to determine the strengths of most of the strong levels in this energy region for Pb208; there are concentrations of strength in a few levels near 5.5 and 7 MeV with the sum of B(E 1)a.
