Definition of Auger effect in English:

Auger effect

noun

Physics
  • A process in which an electron in an outer shell of an atom makes a transition to a vacancy in an inner shell. The energy gained is transferred to an electron that escapes from the atom.

    ‘This is known as the Auger effect or autoionization since the ion has self-ionized after the photoionization event.’
    • ‘The second is the Auger effect, by which the hole left by the excited core electron is filled by an outer electron.’
    • ‘A brief history of the discovery of the Auger effect is given, which is followed by a short description of some of the fields in which this discovery has had a major impact.’
    • ‘This process of resonant photon absorption accompanied by electron emission forms a resonant Auger effect or resonant Auger Raman scattering.’
    • ‘First an electron is captured into a bound state and a bound electron is excited (inverse Auger effect).’
