Q. Write short notes on proton - proton fusion in sun.
Proton - Proton cycle
1H1 + 1H1 → 1H2 + 1e0 + ν (emission of positron as well as neutrino)
1H1 + 1H2 → 2He3 + γ (emission of the gamma rays)
2 2He3 → 2He4 + 2 1H1
The reaction cycle is written since
4 1H1 → 2He4 + 2 1e0 + 2ν + energy (26.7 MeV)
Therefore four protons fuse together to form an alpha particle and two Positrons with a release of large amount of energy.
