Abstract: The light output response of BC501A liquid scintillator to -rays has been studied. The pulseheightspectra of BC501A (Φ5.08 cm x 5.08 cm) for different PMT high voltages have been measured using 137Cs, 60Co γ-ray sources. The Geant4 simulated pulse-height spectra showed a good agreement with experimental data. The energy resolution functions and energy calibration curves have been obtained by comparing measured light output distribution with simulated one. The position of the Compton edge relative to the position of the maximum and the half height of the spectra has also been studied using Geant4 in detail. The value of Nc/Nmax at the position of Compton edge decreases from 0.8 to 0.7 with the increase of incident -rays energy (0.2~0.3
MeV).
