Abstract
Light output, alpha=beta ratio, and pulse shape have been investigated at -25 degrees with PbWO4 crystal scintillators undoped, and doped by F, Eu, Mo, Gd and S. The fast 0.01–0.06 us and middle 0.1–0.5 us components of scintillation decay were observed for all the samples. Slow components of scintillation signal with decay times 1–3 and 13–28 us with total intensity up to about 50% have been recognized for several samples doped by Molybdenum. We found some indications of a pulse-shape discrimination between a particles and gamma quanta with PbWO4 (Mo doped) crystal scintillators.
