A novel simulation for the transfer function of high energy electrons
with initial energy E0 (5 keV less-than-or-equal-to E0 less-than-or-eq
ual-to 15 keV) based in an energy analysis of each stage of the diffus
ion, is presented for CEMS (Conversion Electron Mossbauer Spectroscopy
). The numerical results are in good agreement with ICEMS (Integral Co
nversion Electron Mossbauer Spectroscopy) experimental data and with t
he results of previous simulations.
