An investigation was made of the action of 200-kwp x rays and 2.9-Mev protons on solutions of spproximately lM hydrogen peroxide-16,16 in water which contained 92 to 95 atomic per cent oxygen-18. Resotions were carried out in the presence snd absence of initially added oxygen-16,16 or oxygen-18,18 and in the presence or absence of bromide. The reaction products investigated were oxygen- 16,16, oxygen-16,18, and oxygen-18,18 formed during raniolysis as well as the same species formed from the decomposition of the hydrogen peroxide after irradiation. Results show that hydrogen peroxide-18,18 can be formed through a distinct molecular mechanism from water alone, whereas hydrogen peroxide-16,18 results from reactions of H O radicals or their equivalent with hydrogen peroxide- 16,16 according to the reaction O/sup 18/H + HO/sup 16/ - O H -- HO/sup 18/ - O/ sup 16 / H + O/sup 16/H.
