Differential cross sections for NRA and EBS
Nuclear Reaction Analysis (NRA) and Elastic Backscattering Spectroscopy (EBS) are two of the most commonly used techniques for the quantitative depth profiling of light elements. They are both least destructive and feature high accuracy and sensitivity. NRA additionally features high isotopic selectivity, increased sensitivity for many elements and the possibility of simultaneous analysis of several light elements in near-surface layers. As a result, these techniques are widely used for the analysis of samples and specimens relevant to various disciplines such as biology, geology and cultural heritage, but also for specimens used in a variety of technological applications. However, these techniques rely on experimental cross sections for the investigated nuclear reactions or elastic scattering. The determination of differential cross sections for nuclear reactions and elastic scattering with proton, deuteron, 3He and 4He beams is available in RUBION. Six different detection angles can be measured simultaneously using 6 Silicon Surface Barrier (SSB) detectors at energies suitable for Ion Beam Analysis applications.
