In this communication we present results of measurements of low temperature thermoluminescence, isothermal decays, steady state radioluminescence yield, and scintillation time profiles at various temperatures on two scintillator materials, BaF_{2}:Ce and undoped BaF_{2}. We find that all these results can be consistently interpreted in the frame of a model that includes several relatively shallow charge traps. We have identified and characterized one particular shallow trap that causes the decay of the dominant scintillation component of BaF_{2}:Ce to be slower than radiative, as well as a set of others that are responsible for even slower components in the scintillation time profile of this material.
