New experimental data is presented which displays /sup 137/Cs resolution of both single Si(Li) devices and a detector stack 2 cm in height as a function of temperature (85 K/spl les/T/spl les/245 K). We also discuss variations in photopeak shape which indicate that detector charge collection may be temperature dependent over the range of interest.< >
