Assume that an electron and a position pair is formed from a gamma ray photon having energy 3.0 MeV. Find the total kinetic energy of the positron and the electron that is formed.

A gamma ray photon creates an electron positron pair. If the rest mass energy of an electron is 0.5 MeV and the total kinetic energy of the electron positron pair is 0.78 MeV, then the energy of the gamma ray photon must be

To produce an electron-position pair, the minimum energy of gamma -ray photon must be
