Another set of reactions that result in the fusing ofhydrogen into helium in the Sun and especially in hotter starsis called the carbon cycle. It is12C + 1H → 13N + γ,13N → 13C + e+ + ve,13C + 1H → 14N + γ,14N + 1H → 15O + γ,15O → 15N + e+ + ve,15N + 1H → 12C + 4He.Write down the overall effect of the carbon cycle (as wasdone for the proton-proton cycle in2e− + 41H → 4 He + 2ve + 6γ ). Note the number of protons ( 1H ) required and assume that the positrons ( e+ ) annihilate electrons to form more γ rays.
The Sun generates energy by p-p proton-proton chain nuclear fusion.
The second step of p-p chain is: 2H + 1H → 3He.
The particle masses are 2.0141 u, 1.0078 u, 3.0160 u, for 2H, 1H, 3He, respectively.
This step produces _____ MeV of energy.

- Another series of nuclear reactions that can produce energy in the interior of stars is the carbon cycle first proposed by Hans Bethe in 1939, leading to his Nobel Prize in Physics in 1967. This cycle is most efficient when the central temperature in a star is above 1.6 x 107 K. Because the temperature at the center of the Sun is only 1.5 x 107 K, the following cycle produces less than 10% of the Sun’s energy. (a) A high-energy proton is absorbed by 12C.
