Abstract

Scintillation light is widely believed to be Poisson or super-Poisson. We tested this hypothesis by measuring the temporal correlation between two detectors detecting scintillation light resulting from the same gamma-ray event in SrI₂:Eu . Poisson light is expected to yield zero temporal correlations, while super-Poisson light is expected to yield positive, and sub-Poisson light is expected to yield negative temporal correlation. Scintillation light in SrI₂:Eu was found to be negatively correlated. Therefore, we conclude that the scintillation light in SrI₂:Eu is sub-Poisson.
