Multiple Bremsstrahlung
Abstract
The cross section for the multiple production of photons in bremsstrahlung at high energies is calculated, and it is shown that the probability for multiple bremsstrahlung is quite small compared with that for the ordinary bremsstrahlung even in the very high energy region of cosmic rays. The general problem of multiple photon production is further discussed, and it appears that even at high energies the probability for multiple photon production is appreciable only in the following two cases: (1) an energetic charged particle is deflected through an angle, which is large compared with the ratio of its rest energy and its total energy; (2) an energetic charged particle is annihilated, captured or converted into a neutral particle.
