The relation of pulse height in CsI(Tl) to particle energy for protons, deuterons, and alpha particles was examined below 20 Mev under a variety of experimental conditions. Observed deviations from simple propertionality both constant and quadratic terms in a power series representation) depend upon circuit parameters. For a given apparatus, the deviations vary monotonically with the energy interval represented by one spectrometer charel, and tend to zero in the limit of vanishing channel width. The observations suggest that the intrinsic response of CsI(Tl) in the limit of vanishing instrumental effects deviates from a straight line through the origin by less than 0.1% per Mev. Observed curvatures, for channel widths of order 0.3 to 0.6 Mev, are in the range 0.1 to 1%/Mev for both protons and deuterons. Pulse-height ratios for given energy are iound to be d:p = 1.04(+0.08, -0.02) and alpha :p = 0.50( cores consistin 0.031. Spectrometer peak positions are determined with a precision of 0.1 channel or better by a method of analytic interpolation. (auth)
