Rutherford backscattering spectrometry (RBS) is an analytical technique used in materials science. 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 … 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 … 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 • Nuclear microscopy See more WebRutherford backscattering spectrometry (RBS) allows quantitative compositional analysis without the use of reference standards.
