Rutherford Backscattering Spectrometry (RBS)

Rutherford Backscattering Spectrometry (RBS) is an analytical technique used to determine the composition and structure of materials. It involves directing a beam of high-energy ions, typically helium nuclei, at a sample. When these ions hit the atoms in the material, they scatter backward, and by measuring their energy and number, scientists can identify the types and quantities of elements present and their depth within the sample. RBS is precise and non-destructive, making it valuable for studying thin films, coatings, and layered materials in research and industry.
