摘要：

Expressions for the spectral-angular density of bremsstrahlung from a relativistic electron in a thin layer of matter are obtained. The effect that the multiple scattering of electrons by medium atoms exerts on the spectral-angular features of radiation in a thin amorphous target is studied. It is shown that, if the root-mean-square angle of multiple scattering is much larger than the characteristic angle of relativistic-electron radiation, there occurs the bremsstrahlung-suppression effect, which is similar to the Landau-Pomeranchuk-Migdal effect.
