Effective Atomic Numbers for Fe--Mn Alloy Using Transmission Experiment

The effective atomic numbers (Z_eff) and effective electron density (N_e) 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.
