Definition of Compton effect in English:

Compton effect


  • An increase in wavelength of X-rays or gamma rays that occurs when they are scattered.

    • ‘In 1927 Compton received the Nobel Prize in physics for what is now called the Compton effect.’
    • ‘The Compton effect occurs primarily in the absorption of high X-ray energy and low atomic numbers.’
    • ‘In 1922, while doing research on X rays, Compton discovered what came to be called the Compton effect, for which in 1927 he shared the Nobel Prize in physics.’
    • ‘The Compton effect can also be expressed as a shift in energy between the incident and scattered photon.’
    • ‘Thus there can be no redshift due to the Compton effect unless there is a change in the direction of propagation.’


Early 20th century: named after A. H. Compton (see Compton, Arthur Holly).
