Nuclear pair production
WebPairProduction - University of Toronto Web24 mei 2012 · The pair-production is the process of emission of positron and electron in the nuclear and electronic field. The threshold energies for pair production process in the nuclear and electronic fields are 1.022 MeV and 2.044 MeV, respectively, and thereafter the cross-section increases with increasing the photon energy.

Of these, three major processes are found to be important. They are the Compton effect (az), Photo electric effect (ax) and Pair production (cx). The minor effects are as follows: Rayleigh scattering : (ay) It occurs with tightly bound electrons.
