Pulse-shape discrimination with PbWO4PbWO4 crystal scintillators

Light output, α/βα/β ratio, and pulse shape have been investigated at -25∘C with PbWO4PbWO4 crystal scintillators undoped, and doped by F, Eu, Mo, Gd and S. The fast 0.01–0.06μs and middle 0.1–0.5μs components of scintillation decay were observed for all the samples. Slow components of scintillation signal with decay times 1–3 and 13–28μs with total intensity up to ≈50%≈50% have been recognized for several samples doped by Molybdenum. We found some indications of a pulse-shape discrimination between αα particles and γγ quanta with PbWO4PbWO4 (Mo doped) crystal scintillators.
