A photon of energy E Interacts with an electron at rest and undergoes pair production, producing a positive electron (positron) and an electron (in addition to the original electron): photon + ee+++ The two electrons and the positron move off with identical momenta in the direction of the initial photon. Find the kinetic energy of the three final particles and find the energy F of the photon. (Hint: Conserve momentum and total relativistic energy.) kinetic energy photon energy × Mev × Mev
