摘要：

The total mass attenuation coefficients (mu(m)), for Ti, Ni and TixNi1-x(x = 0.7, 0.6, 0.5, 0.4 and 0.3) alloys were measured at 22.1, 25.0, 59.5 and 88.0 keV photon energies. The samples were irradiated with 10 mCi Cd-109 and 100 mCi Am-241 radioactive point source using transmission arrangement. The gamma- and X-rays were counted by a Si(Li) detector with a resolution of 160 eV at 5.9 keV. Total atomic and electronic cross-sections (sigma(t) and sigma(e)), effective atomic and electron numbers (Z(eff) and N-eff) were determined experimentally and theoretically using the obtained mu(m) values for TixNi1-x alloys. The theoretical An, values of each alloy were estimated using mixture rule. The experimental values were compared with the calculated values for all samples. (C) 2009 Elsevier Ltd.
