Abstract

The possibility of diagnostics of atomic nuclei and electron distribution in a structured material using bremsstrahlung (BS) of relativistic electrons in the material and considering the electric field screening of nuclei by the electrons of the medium is discussed. The alternative calculation technique of the BS spectrum determining a distinctive relation between the frequency-angular BS properties and the relativistic factor of radiating electrons is considered. The dependence of the BS intensity on the screening electron distribution character is analyzed for light and heavy elements. It is shown that, in spite of a sharp decrease in the BS intensity as compared to the radiation for a bare nucleus, the screening does not completely suppress BS, which allows its use for structural analysis of a material.
