Recently, we found that the decay times between α particles and γ photons were different for the recently developed scintillators. We also noticed that α - β ratios were different for these scintillators. We expect that there might be a relation between these two properties. Thus, we measured the α - β ratios and the decay time differences between α particles and γ photons for the newly developed scintillators and investigated the relationship between them. We measured the α - β ratios and decay times for five scintillators: (LaGd)2Si2O7 (LaGPS), Gd2Si2O7 (GPS), ceramic Gd3Al2Ga3O12(GGAG), ceramic (YGd)3(GaAl)5O12:Ce (YGAG), and single-crystal Gd3Al2Ga3O12 (GAGG). After the measurements, we estimated the correlation between the α - β ratios and the decay time differences between α particles and γ photons. Among these scintillators, as the α - β ratios increased, decay time differences decreased with the correlation coefficient ( R2 ) of more than 0.8. We conclude that there was a negative correlation between α - β ratios and the decay time differences between α particles and γ photons for the measured newly developed scintillators.
