The scintillation properties of LaBr[sub 3] doped with 0.5% Ce[sup 3+] are presented. Under optical and gamma ray excitation, Ce[sup 3+] emission is observed to peak at 356 and 387 nm. The scintillation light output is 61 000±5000 photons/MeV at 662 keV. More than 90% is emitted with a decay time of 35 ns. An energy resolution (full width at half maximum over the peak position) of 2.85%±0.05% was observed for the 662 keV full absorption peak. A time resolution of 385 ps was obtained using BaF[sub 2] as second scintillator and gamma rays of [sup 60]Co. © 2001 American Institute of Physics.
