An electron and a positron anihilate with equal and opposite momenta and become two photons: e- + e- → 2 photons. Both the electron and the positron have mass me and momentum of magnitude mac.
(a) Explain why the electron and positron cannot annihilate to become a single photon.
(b) What are the magnitudes of the momenta of the photons?
