Validation of Geant4 low energy physics models against electron energy deposition and backscattering data

A comprehensive and systematic validation of Geant4 electromagnetic physics models, relevant to the low- energy domain (les 1 MeV), was performed. Considering different materials, the energy deposition pattern and backscattering are investigated for electron beams of varying energies and incident angles. The obtained simulation results are compared against high-precision experimental data. The study provides an useful guidance for low-energy physics simulation applications based on the Geant4 toolkit.
