Abstract
English
Light elements are not amenable to most analytical methods. In this work, ion beam analysis was used to detect hydrogen and lithium in materials. For the detection of hydrogen, coincident scattering and the resonant nuclear reaction with N-15 were used to make a quantitative and qualitative statement. For lithium, the nuclear reaction between Li-7 and protons was used to detect the decay products and to determine the depth range from their energy. Furthermore, a setup was developed that provides a detection limit of about 10 ppm lithium.
