Abstract of Publication No. 400
The scintillation properties of LaBr3 doped with 0.5% Ce3+
are presented. Under optical and gamma ray excitation, Ce3+
emission is observed to peak at 356 and 387 nm. The scintillation light output is 61000±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 BaF2 as second scintillator and gamma
rays of 60Co.
