Pair production

  1. Aug 19, 2005 #1
    Is there a short answer why pair production can not happen in empty space, but that photons must interact with an external field?

    thanks and a nice weekend

    oh, just saw someone asked the same question in the nuclei section today and answers already there

    Listen, Go and look for "pair creation" in "Nuclei and particles". The answer is given there.
