Backscattering of MeV Electrons. An Analysis of Tabata’s Experiment with Geant4

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