New interpretations of XPS spectra of nickel metal and oxides
... Beginning with nickel metal ELS, they suggest that more intense features at 6.0 and 9.5 eV are due to surface and bulk plasmon losses respectively with weaker intra- and inter-band transitions at 3.7 and 7.1 eV. In XPS spectra, the well-known satellite 6 eV above the main emission line for Ni 2p3/2 ...

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.
