Abstract

The light output, $\alpha/\beta$ ratio, and pulse shape have been investigated at $-25^\circ$ C with PbWO $_4$ crystal scintillators undoped, and doped by F, Eu, Mo, Gd and S. The fast $0.01-0.06 \mu$ s and middle $0.1-0.5 \mu$ s components of scintillation decay were observed for all the samples. Slow components of scintillation signal with the decay times $1-3 \mu$ s and $13-28 \mu$ s with the total intensity up to $\approx50%$ have been recognized for several samples doped by Molybdenum. We found some indications of a pulse-shape discrimination between $\alpha$ particles and $\gamma$ quanta with PbWO $_4$ (Mo doped) crystal scintillators.
