Paper Abstract

Perhaps the first idea about these processes may be found in a work of Williams (1934) and B. Ferretti (Nuovo Cimento 7, 1 18 (1950). Ferretti developed semi-qualitative calculations based on the Weiszacker-Williams method of the virtual quanta 1. Also Ter-Mikaelian and Purcell, M. L. Ter-Mikaelian (Zh. Eksp. Teor. Fiz. 25, 296 (1953)), E. M. Purcell (private communication, 1955) performed calculations based on the virtual quanta method. Feinberg and Pomeranchuk and Dyson and Uberall (Phys. Rev. 99, 604 (1955)) presented other arguments. But perhaps in the first two most important papers 4,5. H. Uberall carried out the full calculation by using the Born approximation and by obtaining results on the cross sections and polarization which could be compared with experiments. These theoretical results stimulated the performance of experiments by means of the high-energy electron accelerators. But first experimental results were in apparent contradiction with the theoretical ones.
