ENERGY RESOLUTION MEASUREMENTS OF BENZENE, TOLUENE AND CYCLOHEXANE SCINTILLATORS FOR MONOENERGETIC GAMMA-RAYS

Energy resolution and difference of the maximum energy of Compton elec trons from the half-height of the Compton edge was measured experiment ally for benzene (C6H6), cyclohexane (C6H12) and toluene scintillators for monoenergetic gamma-rays using a gamma-gamma coincidence techniqu e. For 0.5-1.2 MeV gamma-rays, the energy resolution for C6H6, C6H12 a nd toluene scintillators varies from 23.8-12.6%, 28.6-2.5% and 23.5-4. 5%, respectively. The corresponding energy difference between the maxi mum Compton electron energy and the half height of the Compton edge fo r 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 det ector agrees within 5-10% of that obtained with an identical C6D6 scin tillator.
