Distribution of particle energy in 3He fusion

[MnemosyneAH]

The 3He-3He fuel cycle releases protons and alpha particles, plus 12.9 MeV of energy. No matter where I look, I can't find any information about how that 12.9 MeV is distributed over the fusion products, every source just quotes the 12.9 total.

Does anyone know how this energy tends to be distributed, or can show me how to derive it (I'm sure there must be an equation, but I'm only a beginner at this, so I can't guess at what it is).

write down the total reaction

3He + 3He -> 2p + 4He + 12.85 MeV ?

 

[ansgar]

3 bodies in the final state means that they all have a contunous energu spectra

Huh, okay then.

Huh, okay then.

just as in beta decay for instance, basic kinematics
