Pair Generation


Pair Generation : Interaction of energy-rich electromagnetic radiation with matter. If the energy of a radiation is greater than 1.02 MeV and thus greater than double the ?rest mass of an electron (me,0 = 0.511 MeV), it is possible to generate an electron-positron pair (materialisation of energy). Pair generation; formation of an electron-positron pair from a gamma quantum rich in energy
