Zusammenfassung:A method for excitation of thorium-229 isomeric nuclei the electron beam irradiation of a solid-state target based on thorium silicate is considered. The key point for obtaining an effective yield of isomeric nuclei is the generation of secondary electrons with a significant increase in the multiplication factor for electrons that have energies within a range from 1 to 25 keV. Based on numerical simulation and theoretical estimation of the excitation cross section of isomeric transition in inelastic scattering, the yield function of isomeric nuclei was o qualitatively obtained.
