摘要：

The mass attenuation coefficients (mu(m)) for organic nonlinear optical materials measured at 122-1330 keV photon energies were investigated on the basis of mixture rule and compared with obtained values of WinXCOM program. It is observed that there is a good agreement between theoretical and experimental values of the samples. All samples were irradiated with six radioactive sources such as Co-57, Ba-133, Na-22, Cs-137, Mn-54 and Co-60 using transmission arrangement. Effective atomic and electron numbers or electron densities (Z(eff) and N-eff), molar extinction coefficient (epsilon), mass energy absorption coefficient (mu(en)/rho) and effective atomic energy absorption cross section (sigma(a,en)) were determined experimentally and theoretically using the obtained mu(m) values for investigated samples and graphs have been plotted. The graph shows that the variation of all samples decreases with increasing photon energy. (C) 2016 Published by Elsevier B.V. This is an open access article under the CC BY-NC-ND license.
