Secondary Electron Radiation from Different Targets Exposed to Photons with Energy 0.1 to 3 MeV

Differential and integral yields of secondary electrons from different targets bombarded by monoenergetic photon beams are calculated using the Monte Carlo method. The results are compared to experimental data and values calculated by other authors. The discovered 20 to 30% decrease of calculated backward yields according to experimental data for heavy elements is explained by the limited applicability of Sauter's formula for the description of photoelectron angular distribution.
