Nuclear fusion is a process where two light atomic nuclei combine to form a heavier nucleus, releasing a significant amount of energy in the process. One of the most common fusion reactions that occur in stars, including our Sun, involves the fusion of hydrogen isotopes. The simplest example of nuclear fusion is the fusion of deuterium and tritium (isotopes of hydrogen):
\[
\text{D} + \text{T} \rightarrow \text{He} + n + 17.6 \, \text{MeV}
\]
Where:
- D is deuterium (\(^2_1H\))
- T is tritium (\(^3_1H\))
- He is helium-4 (\(^4_2He\))
- n is a neutron
- 17.6 MeV is the energy released in the reaction.
Other fusion reactions can involve different isotopes. For example, the proton-proton chain reaction is the primary fusion process in the Sun:
1. Two protons fuse to form deuterium, releasing a positron and a neutrino.
2. Deuterium fuses with another proton to form helium-3.
3. Two helium-3 nuclei can combine to form helium-4, releasing two protons.
Overall, the fusion process can be complex and involves multiple steps and intermediate reactions. The specific reactions can vary, but they all generally release a significant amount of energy.
