Abstract
The relationship between the scintillation efficiency and the specific-energy loss as well as the decay curves of the GSO:Ce crystals with the Ce concentrations of 0.25, 0.5, 1.5 and 2.5 mol% have been investigated under the irradiation of high-energy electron, proton, alpha particle and the fission fragment excitation. The relationship observed in the GSO:Ce crystals is found to be independent from the Ce concentration, and is explained in terms of the concept of ionization quenching proposed by Birks. The quenching efficiency B of GSO:Ce is found to be about 0.005 (g cmâ2/MeV). The measured decay curves showed the independence of the decay curves for excitations of electrons, alpha particles and fission fragments.
