- Abstract: Ion Beam Analysis (IBA) designates a set of atomic-nuclear spectroscopies for material analysis, such as elastic or inelastic ion scattering, proton-induced emission of X or gamma rays, and low energy nuclear reactions. Combined, these techniques can detect and quantify all elements of the periodic table, with detection limits varying from 1 to 100 ppm (¹ g/g). Existing for over 50 years, Ion Beam Analysis techniques are a spino® of Nuclear Physics technologies, making use of the vast accumulated data on stopping power, cross sections, atomic and nuclear energy levels, etc. In some sense, the ¯rst evidence of the nucleated atom by Geiger and Marsden in 1909, was the ¯rst RBS analysis. PIXE analysis started in 1970, with the development of the high resolution X-Ray Si(Li) detector. Since its beginning, IBA techniques are being extensively applied for thin ¯lm (< 1 ¹ m) analysis of semiconductors, environmental, artistical and high-tech materials that need fast, sensitive, precise and nondestructive elemental analysis. Major developments that helped making IBA a widespread analytical tool are: 1) The development of small, cost e®ective and reliable electrostatic accelerators; 2) Development of user friendly and accurate computer programs for the simulation of RBS spectra and for automatic processing of PIXE spectra, either for thin and for thick samples; 3) The development and use of micro-beams and proton/He micro-probes down to limit of 10nm beams; 4) The construction and maintenance of an www accessible and easy to use data base for low energy cross sections and stopping powers for almost all relevant materials, 5) The need for integrated and self-consistent analysis, pushing for better and more reliable cross sections (Gamma, X-ray and Ion-scattering) and stopping power data. 6) The current development of imaging techniques.
