Rutherford Backscattering Spectroscopy (RBS) is an analytical technique based on the elastic scattering of high-energy ions from the nuclei of atoms in a target material. The fundamental principle of RBS relies on the Coulombic interaction between the positively charged incident ions and the atomic nuclei in the sample. When a high-energy ion, typically in the range of 1–3 MeV, strikes
