Textbook Problem

# Two fusion reactions mentioned in the text are n + 3 H → 4 He + γ and n + 1 H → 2 H + γ .But reactions release energy, but the second also creates more fuel. Confirm that the energies produced in the reactions are 20.53 and 2.22 MeV, respectively. Comment on which product nuclide is most tightly bound, 4He or 2H.

To determine

Confirmation that the energies produced in the reactions are 20.58 and 2.22 MeV, respectively

n+H3eH4e+γandn+H1H2+γ

Comment on which product nuclide is most tightly bound, H4e or H2 ?

Explanation

Given info:

â€ƒâ€ƒm(H1)=1.007825032um(H2)=2.014101778um(H3e)=3.0160293Â um(H4e)=4.002602um(n)=1.0086649Â uEnergyÂ ofÂ 1Â uÂ =Â 931.5MeV

Formula used:

Energy,

â€ƒâ€ƒE=Î”mc2

Calculation:

We have,

1. n+H
