SUMMARY
The discussion centers on the annihilation of a positron with kinetic energy of 2.2 MeV colliding with an electron at rest, resulting in the production of gamma photons. The total energy calculated, including rest mass, is 3.222 MeV, derived from the equation (0.511 MeV x 2) + 2.2 MeV. To find the average energy of the two gamma photons produced, the total energy must be divided by two, yielding an average of 1.611 MeV per photon. This calculation resolves the initial confusion regarding the energy distribution in the annihilation process.
