A series of simulations were conducted with Geant4 in order to verify the electron backscattering experiments performed by Tabata in the low Z elements of Be, C and Al. In general, a quite good agreement was obtained by carefully choosing the physics lists employed. These results invalidate the claim made before by Kirihara et al about the presence of experimental errors in Tabata’s work.

Keywords: backscattering coefficient, electron scattering, EGS5 simulation, medium (MeV) energy
