Abstract

In the first Born approximation, differential cross sections of bremsstrahlung passing through an external homogeneous electric field were obtained and numerically analyzed [1]. Two cases of electron motion in an external field are considered: 1.) the electrons emitted by the source fall on the potential barrier of the external field, passing through the lattice of Coulomb centers. 2.) the emitted electrons are accelerated by an external electric field. And after passing through the layers, the Coulomb centers are absorbed by an absolutely black wall (located at a macroscopic distance from the scattering centers). Different configurations of elementary cells are considered. It is shown that when the geometry of the cells is changed, the structure of the bremsstrahlung, due both to the superposition of the motion of the emitted particles in the field of the lattice centers and the external field, and to the interference reflected from the potential barrier of the radiating particles, varies noticeably.
