Özet

The total mass attenuation coefficients (mu/rho), for pure Ti, Co, Cu and TixCo1-x, and CoxCu1-x (x = 0.8, 0.7, 0.6, 0.5, 0.4, 0.3 and 0.2) alloys were measured at 22.1, 25.0, 59.5 and 88.0 keV photon energies. The samples were irradiated with Cd-109 and Am-241 radioactive point source using transmission arrangement. The X- and gamma-rays were counted by a Si(Li) detector with resolution of 160 eV at 5.9 keV. Total atomic and electronic cross-sections (sigma(t) and sigma(e)), effective atomic numbers (Z(eff)) and electron densities (N-el) were determined using the obtained mu/rho values for investigated 3d alloys. The theoretical mass attenuation coefficients were estimated using mixture rule and the experimental values of investigated parameters were compared with the calculated values. (C) 2009 Elsevier B.V.
