Photon Interaction of WO3:BaO:ZnO:B2O3 glasses in energy range 1 keV to 105 keV:Theoretical Calculation

Abstract

The photon interaction, mass attenuation coefficient (m_m), effective atomic number (Z_eff) and effective electron density (N_e) of WO₃:BaO:ZnO:B₂O₃ glasses have been calculated by using WinXCom program in the energy range from 1 keV to 10⁵ keV. The results shown the total and partial interactions varied with the concentration of additive WO₃. At low photon energy found that the photoelectric absorption is the main interaction in energy range 1 keV to 10³ keV, the values were decreased with increasing of photon energy. The values found to be the raised suddenly near the M-, L- and K- absorption edge of WO₃ and show the higher raised when increase WO₃ concentration. The coherent scattering has been found in in energy range 1 keV- 10² keV and the values decreased with increasing of photon energy and increased with increasing of WO₃ concentration. The incoherent scattering is the main photon interaction process in energy range          10¹ keV to 10³ keV , the values were increased with increasing in photon energy range 1 keV-10² keV and decreased in photon energy range 10² keV to 10⁵ keV and increased with increasing of WO₃ concentration. The pair production in nuclear field occurs at photon 1.022x10³ keV and it increases with increase in photon energy. The mass attenuation show the peak at low energy regions which corresponding to the photoelectric absorption edge, the values show the increase with increasing WO₃ concentration. The results of effective atomic numbers and the effective electron densities have peak are corresponding to the M-, L- and K- absorption edge of tungsten and show the stronger peak when increases the concentration of WO₃. These results found to be the same trend with the trend of the mass attenuation.
