“…These ratios have been computed using both theories of electron field pair production. The different experiments in which these data were obtained are listed in Table IV. accurate attenuation experiments above 40 Mev [17][18][19][20][21][22][23][24] have been collected together and compared with theory. The experiments are listed in Table IV.…”

The total cross section for the attenuation of high-energy gamma rays has been measured in various elements. The variation with atomic number, Z, has been observed by measuring the absorption of 1-Bev gamma rays in 12 different elements ranging from hydrogen to uranium. Additional measurements were made in copper at 400 and 700 Mev to show the energy dependence of the absorption processes. These results are then combined with those of other investigators at lower energies and show that the theory of pair production in the nuclear field correctly predicts the cross section as a function of atomic number and photon energy. The measurements in low-Z elements give information on pair production in the field of the electron. The results are in closer agreement to the calculations of Wheeler and Lamb than to the estimate of Joseph and Rohrlich. In addition a short experiment was performed to measure the symmetry of the energy distribution between the electron and positron members of the pair. The results show that the energysharing curve is symmetrical as predicted by theory.

The radiative corrections to the high-energy bremsstrahlung and pair-production spectra are calculated in the Weizsacker-Williams approximation. Results for the soft-photon radiative correction to the spectra are given, and for the case of pair production the soft-plus-hard-photon radiative correction is also obtained. The radiative correction to the total pair-production cross section is found to be practically independent of the photon energy and of the atomic number of the target material. Comparison with available experimental data shows essential agreement within the relatively wide experimental limits.
