Resonant nuclear reaction hydrogen concentration profile

A technique which can yield hydrogen concentration profiles of a glass surface(19) without the complications of ion milling involves using the resonant nuclear reaction between hydrogen 1H) and (1 N). At precisely 6.385 M V (lab) there is a resonance in the reaction 3N + H = X +... 

One technique that has been able to measure hydrogen concentration in a thin film and do a depth profile, without reliance on standards, uses a resonant nuclear reaction technique.16 In this procedure, the nuclear reaction between a hydrogen atom ( H) and an energetic nitrogen-15 atom (1SN) is used. That is... 

NRA gives information about the depth distribution of elements where a nuclear reaction can occur. One reaction often used for the profiling of hydrogen is N ( j, ay)C - at a resonance energy of 6..38S MeV (97]. The detection limit for the ub.solule elemental concentration is 0.1 to I at. %. In special cases the detection limit can be extended to lower concentratioas using standards of known composition. The detection limit for hydrogen using trace analysis techniques is currently 10 ppma (98).
