Photon interaction of molybdenum (Mo) based cesium tri-molybdate (Cs₂Mo₃O₁₀) and disodium dimolybdate (Na₂Mo₂O₇) single crystal scintillators

Both single crystals, molybdenum-based cesium tri-molybdate and disodium dimolybdate single crystal scintillators were investigated for gamma-rays interaction. The theoretical mass attenuation coefficients have been calculated by the WinXCom program. The ¹³⁷Cs source was used in the experiment that was irradiated with eight different photon energies using the Compton scattering technique. The theoretical result shows that the mass attenuation coefficient of both scintillators depends on photon energy and decreases with increasing of photon energy. The molybdenum-based cesium tri-molybdate shows higher values of the mass attenuation coefficient than disodium dimolybdate scintillator all the energy range. The experimental result shows the same trend and are good agreement with theoretical. The values of molybdenum-based cesium tri-molybdate show decreased from 22.15 to 7.7 ( × 10⁻² cm²/g) and the disodium dimolybdate scintillator shows decreased from 16.05 to 7.4 ( × 10⁻² cm²/g). Moreover, the partial interaction, the effective atomic number, and the effective electron density were also investigated.
