Sometimes referred to as high-energy ion scattering (HEIS) spectrometry, RBS is used to determine the structure and composition of materials by measuring the backscattering of a beam of high energy ions … See more Rutherford backscattering spectrometry is named after Lord Rutherford, a physicist sometimes referred to as the father of nuclear physics. Rutherford supervised a series of experiments carried out by Hans Geiger See more We describe Rutherford backscattering as an elastic, hard-sphere collision between a high kinetic energy particle from the incident beam (the projectile) and a stationary particle located in the sample (the target). Elastic in this context means that no energy is … See more The energy loss of a backscattered ion is dependent on two processes: the energy lost in scattering events with sample nuclei, and the energy lost to small-angle scattering from the … See more While RBS is generally used to measure the bulk composition and structure of a sample, it is possible to obtain some information about the structure and composition of the sample surface. When the signal is channeled to remove the bulk signal, careful … See more An RBS instrument generally includes three essential components: • An ion source, usually alpha particles (He ions) or, less commonly, protons. • A linear particle accelerator capable of accelerating incident ions to high energies, usually in the range 1-3 MeV. See more To fully understand the interaction of an incident beam of nuclei with a crystalline structure, it is necessary to comprehend two more key concepts: blocking and channeling. When a beam of ions with parallel trajectories is … See more • Collision cascade • Elastic recoil detection • Geiger–Marsden experiment • Ion beam analysis See more

WebRutherford backscattering spectrometry (RBS) is an ion scattering technique used for compositional thin film analysis. RBS is unique in that it allows quantification without the use of reference standards. During an RBS analysis, high-energy (MeV) He 2+ ions (i.e., α particles) are directed onto the sample and the energy distribution and yield of the … dutch shipyard shelving
