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 in the low Z elements of Be, C, and Al. In general, quite good agreement was obtained by carefully choosing the physics lists employed. These results invalidate the claim made before about the presence of experimental errors in the above work.
