BTW,gamma photons are not produced at reaction 2 1H --> 2He, as it is extremely unstable isotop with negative binding energy, neither at conversion to deuterium. They are produced in 2nd major reaction D + H --> 3He, and by electron positron anihilation. http://csep10.phys.utk.edu/astr162/lect/energy/ppchain.html > >> Kinetic energy follows here momentum conservation. > > Yes (insofar as one is willing to ascribe coherent meaning to that > incoherent statement).
