Question Backscattering Validation 

Forum: Physics List
Date: 31 Oct, 2014
From: A. Hod <A. Hod>

Dear all,

I calculated the coefficient of backscattered electrons from silicon, carbon, aluminum and gold layers of 200 um thickness with Geant4. The calculated backscattered coefficients are:

Backscattering coefficient n= number of scattered primary electrons/number of incident electrons.

Carbon (Z=6): n= 10.81%

Aluminium(Z=13): n=19.09%

Silicon(Z=14): n=21.30%

Gadolinium (Z=64): n=46.02%

Gold (Z=79)= n=49.11%

Additional information:

Physics model: low energy EM physics (Livermore model)

Layers: 1mm x 1mm x 0.2 mm

Cut= 1 um

Energy of normally incident electrons: Ee=300 keV

I would like to validate my calculation. Could you please suggest some references concerning the calculation of the backscattered electron coefficient? Thanks in advance and I kindly welcome your cooperation.

With kind regards

A.H.
