The Klein-Nishima formula gives the generalized formula for both this and the Thomson effect for all frequencies.
Its namesake edge is formed in gamma ray spectroscopy when a gamma ray scatters off the detector because of this effect. The Klein-Nishima formula gives the generalized formula for both this and the Thomson effect for all frequencies. The inverse of this effect can be observed when photons in the cosmic microwave background interact with hot gas near a galaxy group, known as the (*) Sunyaev-Zeldovich effect. The change in wavelength from this effect is equal to Planck's constant divided by the mass of an electron and the speed of light multiplied by one minus the cosine of the scattering angle. For 10 points, name this effect in which a high frequency photon loses energy when it interacts with matter, and inelastic effect named for an American scientist.
