Abstract

The differential cross section for bremsstrahlung during collisions between electrons and a charged particle in an external quasi-uniform and quasi-steady electric field may differ significantly (even when this electric field is far below the atomic field) from that in the absence of an external field. This is explained by the interference of the scattering charged particle while they are reflected from the potential barrier of the external electric field. In this paper, the influence of a electric field of the crystal surface on the bremsstrahlung during collisions between the electrons falling on a potential barrier of this field and a charged particle, when additional interference of the electrons in their initial states appears, was considered. The differential cross section for the bremsstrahlung in this electrid field was calculated using the nonrlativistic Born approximation and the wave functions describe the current density of electrons in an external electric field or the electric field of the crystal surface.© (2005) COPYRIGHT SPIE--The International Society for Optical Engineering.
