Klein-Nishina formula

(formula for the effects of electrons scattering photons)

The Klein-Nishina formula is an equation yielding the differential cross section of a free electron that is scattering a photon, either Thomson scattering or Compton scattering, depending upon the frequency of the EMR. It was an improvement on the Thomson scattering formula. The differential cross section can be a stepping stone to calculating other values.
