Energy Distribution at Large Angles of High-Energy Electrons in Bremsstrahlung

The energy distribution of high-energy electrons, that have been scattered by the nuclear potential and have lost energy by bremsstrahlung, has been investigated. It has been found that there is a peak in the energy distribution which occurs at energies of the order of $m{c}^2$. The nature of and reasons for the peak are discussed. Formulas for the energy distribution near the peak and for the area under the peak are given. Similar results apply also to pair production.
