词汇 Mössbauer effect
释义

Definition of Mössbauer effect in English:

Mössbauer effect

nounˈməːsbaʊəˈməsˌbouər iˌfekt
Chemistry
  • An effect in which certain atomic nuclei bound in a crystal emit gamma rays of sharply defined frequency which can be used as a probe of energy levels in other nuclei.

    〔化〕穆斯堡尔效应

    Example sentencesExamples
    • The Mössbauer effect is a recoilless absorption and emission of a photon.
    • It is this recoilless emission which is called the Mössbauer effect.
    • Using the Mössbauer effect to measure the velocity of the basilar membrane, he made a significant discovery.
    • Isolated nuclei will not exhibit the Mössbauer effect because their motions cause Doppler shifts in the energies of the ray and the peak resonant energy producing a mismatch in these energies.
    • The Mössbauer effect has also been used to verify the prediction of gravitational redshift (the frequency of electromagnetic radiation is dependent on the strength of the gravitational field).

Origin

1960s: named after Rudolf L. Mössbauer (born 1929), German physicist.
