... In a simple ion, one nucleus is present, but the species carries a charge because the number of electrons does not equal the +ve charge on the nucleus. This means that the atom has either lost or gained one or more electrons........ A gain of electrons results in a negatively charged ion; known as a ...

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.
