Fr.: effet Compton
Increase in the wavelength of an → X-ray or → gamma ray → photon when it collides a → free → electron. The photon transfers part of its energy to the electron, the electron recoils, and the photon itself is scattered at a reduced energy.
inverse Compton effect
oskar-e Compton-e vârun
Fr.: effet Compton inverse
A → scattering process by which fast-moving, energetic particles transfer energy to photons, decreasing the wavelength of the radiation. This is a particularly important effect in astrophysics and cosmology since it explains the → Sunyaev-Zel'dovich effect.
