Taking into account that the most abundant heavy elements (C, O, Si etc.) are fully ionized at T & 106 K, one can assume that the absorption is mostly determined by the hydrogen-like ions of heavy elements. Accor ...

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.
