We analyzed the scintillation properties of Ce:Gd3Al2Ga3O12 (GAGG), which are dependent on linear energy transfer (LET). The rise in the scintillation temporal profiles was slow at high LET, whereas the decay did not significantly depend on LET. The slow rise at high LET could be explained as follows. Competition among multiple excited states for energy transfer to a nearby Ce3+ ion led to failure in energy transfer for some of the excited states. Subsequent competition occurred among the residual excited states for energy transfer to the Ce3+ ions located far from the original position of the excited states, followed by quenching.
