Energy resolution measurements of benzene, toluene and cyclohexane scintillators for monoenergetic γ-rays

Energy resolution and difference of the maximum energy of Compton electrons from the half-height of the Compton edge was measured experimentally for benzene (C₆H₆), cyclohexane (C₆H₁₂) and toluene scintillators for monoenergetic γ-rays using a γ-γ coincidence technique. For 0.5-1.2 MeV γ-rays, the energy resolution for C₆H₆, C₆H₁₂ and toluene scintillators varies from 23.8-12.6%, 28.6-2.5% and 23.5-4.6%, respectively. The corresponding energy difference between the maximum Compton electron energy and the half height of the Compton edge for C₆H₆, C₆H₁₂ and toluene scintillators varies from 13.2-7.6%, 17.7-10.2% and 10.2-6.8%, respectively. The energy resolution of the C₆H₆ detector agrees within 5-10% of that obtained with an identical C₆D₆ scintillator.
