Nuclear Reaction Analysis (NRA) is used to measure low-Z elements (e.g. carbon, nitrogen, oxygen, and boron) in thin films. During NRA analysis, the primary projectile induces a nuclear reaction with the low-Z nuclei in the thin film, leading to the ejection of particles with kinetic energies characteristic of specific nuclear reactions (i.e. particular elements).
Very few labs can offer NRA commercially, or match EAG’s depth and breadth of experience, accurate data, and person-to-person service.
NRA can be used to quantitatively measure the total concentration of B, C, N, O and Li present in a film. These elements can be measured at a much lower concentration using NRA compared to RBS. By performing NRA in combination with RBS, the concentrations of light elements in thin films can be determined.
