Fast scintillation light from CaMoO4 crystals

We report the observation of multi-exponential scintillation light emission from a CaMoO4 crystal with slow and fast components after both alpha-particles or gamma-quanta irradiation. The slow components with decay times of similar to 5 and similar to 15 mu s produce the main contribution to the light yield. Whereas the fast components with similar to 10-50ns decay times observed for the first time with such a crystal at room temperature contribute <1% to the crystal total light yield.
