Question

During the discussion, you should have computed the energy of photon pairs created in the annihilation of electron and positron traveling head-on at a speed of 0.6 c. If instead a proton and anti-proton, also traveling at 0.6 c, annihilate, how will be the energy of resulting photons compare to the original case? Question 2 options: Energy of photons coming from proton-anti-proton annihilations will be higher. Energy of photons will be the same Energy of photons coming from proton-anti-proton annihilations will be lower.

Explanation / Answer

(E_{photon} = gamma m c^2 propto m ) ==> (As ( m_{proton} > m_{electron} ) ). Energy of photons coming from proton-anti-proton annihilations will be higher.
