Polycrystalline ice was irradiated at 4.2 K with 3 Mev x-rays. ESR spectra were taken continuously from 4.2 K to 200 K. A radical which is thermally reversible, was observed at 4.2 K in addition to the spectra of the hydroxyl radical, the hydrogen atom radical, and the trapped electron. This reversible radical is also present in ice irradiated at 77 K and cooled to 4.2 K, but in smaller amounts. This radical with the same maximum g-value, g=2.08, but a narrower line width, was also observed in polycrystalline D/sub 2/O irradiated at 4.2 K.
