Electron Capture in Pair Production

  1. Sep 1, 2011 #1
    During electron-positron pair production, does electron capture always happen?

    Gracias

    I doubt it. If the velocity is high enough after production then I don't think the electron would be captured usually. I'm not that knowledgeable on this, so don't take my word for it though.

    I was thinking the same thing. Could someone confirm this please?

    Gracias

    After pair production, the electron and positron will both fly off. Eventually the electron will slow down while the positron will be annihilated.
