The effect of ionization dcnsity on the decay time in CsI(Tl), KI(Tl), and NaI(Tl) crystals was investigated at room temperature. Alpha particles of 4 Mev, protons of 2.7 Mev, and the electrons liberated in the crystal by ThC'' gamma radiation were used as characteristic particles. The effect was determined by a measurement of the rise time of the pulse to its complete height. The results show a dependence of the pulse rise on the particle type in all three crystals. The particles of highest ionization density produced the most rapid pulse rise. The effect is most decided in the CsI(Tl) crystals. The method for the measurement of the pulse was simplified for the CsI(Tl) crystals. (J.S.R.)
