摘要The effective atomic numbers (Zeff) and effective electron density (Ne) for Fe--Mn alloy with different Mn contents are calculated using the mass attenuation coefficients μ/ρ 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 1332keV.
