单词 Auger effect
释义

Definition of Auger effect in English:

Auger effect

nounˈəʊʒeɪōˈZHā əˌfekt
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.

    〔物理〕俄歇效应,自电离

    Example sentencesExamples
    • First an electron is captured into a bound state and a bound electron is excited (inverse Auger effect).
    • This process of resonant photon absorption accompanied by electron emission forms a resonant Auger effect or resonant Auger Raman scattering.
    • 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 is known as the Auger effect or autoionization since the ion has self-ionized after the photoionization event.

Origin

1930s: named after Pierre V. Auger (1899–1993), French physicist.

Definition of Auger effect in US English:

Auger effect

nounōˈZHā əˌfekt
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.
