Assigning effective atomic number and electron density for some lanthanide oxides over wide gamma-rays energies

In the present work, we study the interaction of gamma-rays with oxides of lanthanides, namely lanthanum oxide (La2O3) and europium oxide (Eu2O3). Variation of mass attenuation coefficient values with gamma-ray photon energy is calculated using WinXcom software package in the energy range 1 keV to 103 MeV. The total mass attenuation coefficient values are further used to assign the effective atomic number Zeff and the electron density Ne for these lanthanide oxides. The results obtained for effective atomic number are also compared with the experimental data.In the present work, we study the interaction of gamma-rays with oxides of lanthanides, namely lanthanum oxide (La2O3) and europium oxide (Eu2O3).
