The effective atomic numbers (Zeff) and effective density (Ne) for Fe-Mn alloy with different Mn contents are calculated using the mass attenuation coefficients mu/rho obtained via XCOM in the photon energy range of 1keV-1GeV. The results are compared with the values measured at the photon energy of 662, 1170 and 1332 keV.
