Introduction. Auger Electron Spectroscopy (AES) is based on the Auger effect—a chain of radiationless transitions in an atom in which one of its inner levels is ionized. This process ends by the ejection of an electron, which is known as an Auger electron.

Detecting photoelectrons that are ejected by x-rays is called x-ray photoelectron spectroscopy (XPS) also known as electron spectroscopy for chemical analysis (ESCA).

Detecting electrons that are ejected from higher orbitals to conserve energy during electron transitions is called Auger electron spectroscopy (AES).

Auger electron spectroscopy is a common analytical technique used specifically in the study of surfaces and, more generally, in the area of materials science. Underlying the spectroscopic technique is the Auger effect, as it has come to be called, which is based on the analysis of energetic electrons emitted from an excited atom after a series of internal relaxation events.

The Auger effect was discovered independently by both Lise Meitner and Pierre Auger. Electron energy analyzer Five-layer mu-metal box. Each layer is about 5 mm thick. It reduces the Earth's magnetic field inside by about times.
