Paper Abstract

The results of theoretical investigation of multiple scattering effect on spectral, angular and polarization characteristics of radiation by a relativistic electron passing through a thin amorphous target (with respect to a coherence length) are presented. It is shown that due to this effect the radiation spectrum may essentially differ from the both predictions of the Bethe-Heitler theory of bremsstrahlung and results of the Migdal theory of the Landau-Pomeranchuk-Migdal effect (LPM). It is also shown that non-dipole regime of radiation in the case of intensive multiple scattering leads to significant changes of angular distribution of emitted gamma-quanta and, as a result, to a new possibility for getting highly linear polarized gamma-quanta. The conditions for experimental observation of these effects are discussed.
