Change the wavelength using the slider. The further a point on the resulting loop is, the greater the likelihood at said angle.
The Klein–Nishina formula describes how likely a photon is to scatter off an electron at a given angle during Compton scattering, giving the probability per unit solid angle of scattering in that direction. In simpler terms, it tells us how likely a photon is to bounce off an electron in a particular direction.
