摘要
The cross section for double bremsstrahlung differential in the radiated photon energies and angles has been measured for 70-keV electrons on targets of Al, Cu, Ag, Tb, and U for photons radiated at +/- 45-degrees to the incident beam for photon energies in windows from 10 to 30 keV. In contrast with previous experiments at +/- 90-degrees, the results are in reasonable agreement with the relativistic first Born approximation at lower Z. However, the results exhibit a Z dependence which disagrees with the first Born Z2 dependence, suggesting the need for consideration of a second Born approximation.
