We present laboratory studies of the radiolysis of pure (97%) solid H{sub 2}O{sub 2} films by 50 keV H{sup +} at 17 K. Using UV-visible and infrared reflectance spectroscopies, a quartz-crystal microbalance, and a mass spectrometer, we measured the absolute concentrations of the H{sub 2}O, O{sub 2}, H{sub 2}O{sub 2}, and O{sub 3} products as a function of irradiation fluence. Ozone was identified by both UV and infrared spectroscopies and O{sub 2} from its forbidden transition in the infrared at 1550 cm{sup -1}. From the measurements we derive radiation yields, which we find to be particularly high for the decomposition of hydrogen peroxide; this can be explained by the occurrence of a chemical chain reaction.
