| Abstract: | Tritons accelerated up to 3.5 MeV by a Van de Graaff, were used to study the16O(T, n)18F reaction, which was then applied to the analysis of oxygen in metals and semiconductors. The calculated sensitivity for
the determination of oxygen is 0.5 ppb at 3.5 MeV. Si, Ti and Mo were analyzed non-destructively at 3.5 MeV and the results
agreed with results obtained by other methods. Pure Ge and AsGa were analyzed non-destructively at 3 MeV and the detection
limits were respectively 25 and 6 ppb. |
