Among ion-beam-based analytical methods, direct observation of nuclear reactions induced by highly energetic (Me V domain) charged particles is dedicated to quantitative determination of volumic distributions of light elements from Z = 1 (H) to Z = 41 (Ga) in the near surface region of solids. In most cases, discrimination between their isotopes is enabled up to 37Cl. The incident ions are generally protons, deuterons, helium-3, or helium-4 ions. Nuclear reactions induced by heavier ions are rarely used, mostly for hydrogen depth profiling. All these reactions are characterized by the prompt emission of charged particles (protons or helium-4 ions) and/or γ-rays. Nuclear reaction analysis (NRA), performed in ion millibeam or microbeam modes, is an efficient complement to charged-particle-induced X-ray emission, Rutherford backscattering spectrometry, and elastic recoil detection methods. Its applications are all intended for either absolute quantification or tracing experiments. They cover a broad panorama from life sciences to cultural heritage artifacts, including metallurgy, Earth sciences, nanotechnology, and material science.
