Abstract: The total mass attenuation coefficients (μ/ρ) for pure {Au}
and Au_{99}{Be}_{1}, Au_{88}{Ge}_{12},
{Au}_{95} Zn_{5} alloys were measured at
59.5 and 88.0 keV photon energies. The samples were irradiated with
^{241}Am and ^{109}Cd radioactive point
source using transmission arrangement. The γ- rays were counted by a
Si(Li) detector with resolution of 160 eV at 5.9 keV. Total atomic and
electronic cross-sections (σ _t and σ _e), effective atomic and electron densities
(Z_{eff} and N_{el}) were determined
using the obtained mass attenuation coefficients for investigated Au alloys.
The theoretical mass attenuation coefficients of each alloy were estimated
using mixture rule.
