Auger featuresAuger electron emission occurs also when x-rays impinge a sample. Augerelectron is initiated by the creation of an ion with an inner shell vacancy.surveyAuger electrons are emittedx 10in the relaxation of the excited480Cu 2p Peaks70ion. An electron from a higherlying energy level fills the inner60shell vacancy with the simultaneous 50emission of an Auger electron.40It is a three-electron process.3 Distinct Auger Peaks areseen in the data for CopperCPS302010Cu2sWashington State University--Pullman, WACu Auger Peaks1200 1000 800 600 400 200 0Binding Energy (eV)O1sCu3sCu3p
