Interaction of Radiation with Matter

In passing through matter, the intensity of the radiation is reduced (attenuation), both because some radiation energy is taken Up by material (absorption) and some is deflected from its original path to travel in a new direction (scattering). It should be noted that any effect of radiation on matte ...

Rutherford backscattering spectrometry
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 (typically protons or alpha particles) impinging on a sample.
