Abstract

For a given energy deposited, the Fano factor of a scintillator is defined as the ratio of the variance of the number of scintillation photons to the mean number of scintillation photons. Correlations in time between the signals from two photomultiplier tubes collecting light from the same scintillation event were used to estimate the Fano factor of scintillators. At 662 KeV, LaBr₃:Ce was found to be sub-Poisson, while YAP:Ce was found to be close to Poisson.
