The oxygen content of titanium metal was determined by bombarding samples with 14 MeV neutrons from a Cockcroft-Walton machine and measuring the 7.35 second nitrogen-16 gamma activity produced by the reaction 16O(n, p)16N. In this paper, optimum condition for the measurement of gamma rays of 16N, a correction for the absorption of gamma-rays by samples are discussed. The analytical results by this method are in good agreement with those by the vacuum fusion method. The sensitivity for oxygen is about 1000 counts/mg of oxygen and the standard deviation of the method at the level of oxygen concentration 0.1% is 4%.
This method may be used to study the accuracy and the precision of the conventional method because the method is non-destructive.
