Abstract :
Light output, α / β ratio, and pulse shape have been investigated at - 25 ∘ C with PbWO 4 crystal scintillators undoped, and doped by F, Eu, Mo, Gd and S. The fast 0.01– 0.06 μ s and middle 0.1– 0.5 μ s components of scintillation decay were observed for all the samples. Slow components of scintillation signal with decay times 1–3 and 13– 28 μ s with total intensity up to ≈ 50 % have been recognized for several samples doped by Molybdenum. We found some indications of a pulse-shape discrimination between α particles and γ quanta with PbWO 4 (Mo doped) crystal scintillators.
