Total photon cross sections are measured, using the transmission method in the heavy elements U, Th, Pb, and Au at energies of 30.9, 35.9, and 55.4 keV, to study the photoelectric interaction below the K edges of these elements. A krypton-filled proportional counter with a 512-channel analyzer is used as the detector of photons. The photoelectric cross sections, obtained by subtracting the small scattering contributions from the total cross section, are compared with theoretical predictions of Scofield and of Storm and Israel. General agreement is obtained, except for U and Th at 30.9 keV where the present experimental values show a slight preference to the calculations of Storm and Israel rather than the theoretical ones used by Scofield.
