WebRutherford backscattering spectrometry (RBS) allows quantitative compositional analysis without the use of reference standards. For analysis, high-energy He 2+ ions are directed onto the sample and the yield of the backscattered He 2+ … WebRutherford backscattering spectroscopy (RBS, named after British physicist Ernest Rutherford) operates on the same principle as ISS. A primary ion beam is elastically scattered, and the energy and angle of the scattered ion yield information about the mass of the scattering atom in the sample. RBS differs from ISS by using a higher-energy ...

WebHR-RBS is also called Medium Energy Ion Scattering Spectrometry (MEIS), due to the slightly lower kinetic energies (several hundred keV) in the primary ion beam as compared with standard RBS (which uses 1-5 MeV). The reduced energy of the probe beam enables an enhanced depth resolution of 1 nm for profiling experiments, and furthermore negates ...
