Abstract

We analyzed the effects of the excitation density or linear energy transfer (LET) on the scintillation temporal profiles of Gd₂SiO₅(GSO):Ce by using pulsed ion beams of 20 MeV H⁺, 50 MeV He²⁺, and 220 MeV C⁵⁺. The rise was faster at higher LET, while the decay was similar at largely different LETs. The LET effects on the rise are explained in terms of the competition between the quenching owing to the interaction between the ⁶P_J excited states at neighboring Gd³⁺ ions and the energy transfer to Ce³⁺ ions.
