09307 IUPAC Gold Book - Auger electron spectrum 10.1351/goldbook.09307 09307 current 1 Plot of intensity of Auger electrons as a function of the electron kinetic energy, usually as part of the energy distribution of detected electrons. When excited by incident electrons, the energy distribution of detected electrons, often measured between \(\pu{0 eV}\) and \(\pu{2500 eV}\), contains Auger electrons, backscattered (primary) electrons, and secondary electrons. The entire distribution is sometimes referred to as an Auger electron spectrum. The Auger electron spectrum can be presented in either direct spectrum or differential spectrum formats. backscattered (primary) electrons https://goldbook.iupac.org//terms/view/09311 differential spectrum https://goldbook.iupac.org//terms/view/09319 direct spectrum https://goldbook.iupac.org//terms/view/09320 PAC, 2020, 92, 1781.
