Q. Write short notes on proton - proton fusion in sun.

Proton - Proton cycle

1H1 + 1H11H2 + 1e0 + ν (emission of positron as well as neutrino)

1H1 + 1H2 2He3 + γ (emission of the gamma rays)

2 2He32He4 + 2 1H1

The reaction cycle is written since

4 1H12He4 + 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.
