Determination of effective atomic numbers and electron densities from mass attenuation coefficients for some selected complexes containing lanthanides

The effective atomic numbers and electron densities for the pure elemental forms of Gadolinium (Gd), Dysprosium (Dy), Erbium (Er), and Ytterbium (Yb) and their some selected complexes were obtained from the measured total mass attenuation coefficients at 13.92, 17.75, 20.78, 26.34 and 59.54 keV photon energies using a high-resolution Si(Li) detector by adopting transmission geometry. The measured results were compared with the two different theoretical results. Within experimental deviations, our data are in good agreement with the theoretical values. The obtained parameters were also interpreted with some selected chemical parameters.The accepted manuscript in pdf format is listed with the files at the bottom of this page.
