1. Above twice this ( ) pair production may take place. 2. Compton scattering and pair production are examples of two other competing mechanisms. 3. :The canonical example of creating something from nothing is Pair production . 4. :Antimatter is only made in pair production with matter. 5. Supernova SN 2006gy is hypothesized to have been a pair production type supernova. 6. :: See Gamma ray # Properties # Matter Interaction, Pair production . 7. VHE photons coming from cosmological distances are attenuated by pair production with EBL photons. 8. Another example is pair production in very strong electric fields, sometimes called vacuum decay. 9. Neutral particles with internal quantum numbers can mix with each other through virtual pair production . 10. See Pair production for the full story.
