OSTI ID:4266752
Small quantities of oxygcn in metals and other materials werc identified by N/sup 16/ studied. The radiation produced in reactions O/sup 16/(n,p) (49 mb cross section) during thc irradiation of specimens by l4-Mev neutrons. The very short half life of N/sup 16/(Tsub 1/2/ = 7.3 sec) prevented thc radiochemical separation of nitrogen; however, the high energy of thc studied. The particles (up to l0 Mev) was very effective in measuring the activity of the irradiated specimen. Experiments were also conducted for determining the oxygen in specimens by the rcaction O/sup 16/(T n)F/sup 18/; the results of both experiments were identical. Thc radioactivation analysls by l4-Mev neutrons was carried out with silicon and phosphorus by the reaction S/sup 28/(n,p)Al/sup 28/ with 220 mb cross section and P/sup 31/(n, alpha )Al/sup 28/ with 146 mb cross section. The method was also used for determining sulfur and chloride in organic complexes of ether methacrylate, paraffin, etc., and phosphorus, sulfur, and chloridc in graphite. (R.V.J.)
