Homework Help: Equation for neutron proton-fusion, and deuterium photodiss.

  1. May 10, 2015 #1
    1. The problem statement, all variables and given/known data
    Write the equations for neutron and proton fusion to form deuterium and for deuterium photodissociation.

    2. Relevant equations

    3. The attempt at a solution
    There is plenty on proton-proton fusion to form deuterium, but not much on proton-neutron.

    Is it simply p + n -> D ?

    Is deuterium photodissociation D + γ -> p + n ?

    p + n -> D is forbidden by energy conservation. Some energy has to get dissipated, mainly as photon emission.
