摘要：

The cross-sections of the N-14(He-3, p(i))O-16 (i = 1 2,3,4,5,7) and N-14(He-3, alpha0)N-13 reactions have been measured for He-3 incident energies between 1.6 and 2.8 MeV. These reactions offer an alternative to the N-14(d,p)N-15 and N-14(d, alpha)C-12 nuclear reactions for profiling of nitrogen in the first few microns below the surface. The technique has been applied to tool steels treated by Plasma Immersion Ion Implantation, where treatment at elevated temperatures leads to diffusion of the nitrogen to depths well beyond the implantation range. Simultaneous measurement of the carbon profile can be made using the C-12(He-3, p)N-14 reactions.
