Inverse Beta decay

  1. Apr 6, 2010 #1
    1. The problem statement, all variables and given/known data

    Why is the inverse Beta decay forbidden for a free proton?

    2. Relevant equations

    p -> n + e(+)(positron) + v (neutrino)

    3. The attempt at a solution

    Is it because, the change in the Q value must be the same for each decay?

    The charge balances out, so it's not a problem with charge conservation. Think energy.
