why is deuterium-tritium reaction the most promising nuclear fusion reaction for future energy production?

The deuterium-tritium (DT, Figure 2) reaction is the most useful for fusion energy because it most easily overcomes the Coulomb repulsion, and it has the highest energy release among laboratory-feasible reactions.

Explanation:

When a deuterium nucleus (2H) and a tritium nucleus (3H) combine, the result is a helium nucleus and a very energetic neutron. Under the right circumstances, the energy released is sufficient to induce further fusion reactions.

The deuterium-deuterium fusion divides it's output energy between neutrons and protons.

Explanation:

A large amount of energy is released by nuclear fusion reactioms.It seems that for power generation, the deuterium-tritium reaction is the most practical,but it provides most of the energy to the released neutron...
