WebIn light elements, emission of an Auger electron is common. However, the energy and the total number of electrons released from the atom may be modulated by shake-up and … WebThis energy might eject a third electron from another orbit. By measuring the energy of the emitter electron, called the Auger electron, the atom can be identified. Different atoms have different atomic orbits and therefore different Auger energies. One of the techniques for measuring the energy of the Auger electrons is the same as the LEED setup.
