Description

The authors introduce the problem of electron radiation in a given field of a separate atom and then study the influence of multiple scattering of a particle on the radiation. The authors also introduce the Landau Pomeranchuk effect (19530 consisting of the reduction of probability of radiation of the relativistic electron in an amorphous medium and consider in detail the contribution of the fundamental work by Migdal in 1954 and 1956. These methods have been developed significantly and the review describes the current applications.
