Meaning of Auger effect in English:

Auger effect

Pronunciation /ˈəʊʒeɪ/

noun

Physics
  • An effect whereby an atom which has been ionized by removal of an electron from an inner shell loses energy by emitting an electron from an outer shell.

    ‘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).’

Origin

1920s named after Pierre V. Auger (1899–1993), French physicist.
