I Nuclear reactions

  1. May 7, 2016 #1
    Hello all,

    Assume we have a deuterium-tritium reaction. The energy released is 17.6 MeV. I know from solved examples that neutrons carry 14.1 MeV and Helium carries 3.5 MeV. How do I calculate these numbers (14.1 MeV and 3.5 MeV)?

    Energy and momentum conservation. Assume that the lab frame is the center of mass frame, and then see how to distribute the energy to give both the same momentum (just with opposite sign).

    Looks like the energy is shared between the products inversely proportional to their mass
