WebThe Compton eﬀect is the elastic scattering of photons from electrons. As a reaction, the process is: γ +e −→ γ +e . Since this is a two body elastic scattering process, the angle of the scat-tered photon is completely correlated with the energy of the scattered photon by energy and momentum conservation. This relation is usually ...
