Nuclear energy release question

In summary, when a proton and neutron are streamed towards each other at 2 GeV, the fusion cross section is likely to be infinitesimal due to being above the pion and rho-meson production thresholds. Additionally, the extra energy is more likely to go into the production of secondary particles, such as pions, in an inelastic scattering event due to the conservation of energy.

A proton and neutron "at rest" may stick to each other forming a deuterium and releasing some 2.2 MeV energy but what if they are streamed to each other at 2 GeV? what will be the output of energy? Do we get more kinetic energy in the form of photons?

EDIT: Forgot to address a main point: conservation of energy.

Remember that energy is always conserved. So the 2 GeV of kinetic energy plus the rest mass of the proton and neutron, must also be somewhere in the final state after the reaction.

At 2 GeV kinetic energy, the fusion cross section for pn is likely to be infinitesimal. I don't know off hand its exact value.

You are way above the pion production threshold of 290 MeV and above even the rho-meson threshold at that point. Also you are above the Delta(1232) energy, so particle production via resonance is likely.

So you would much more likely see the extra energy go into the production of secondary particles (mainly pions) in an inelastic scattering event.
 

1. What is nuclear energy release?

Nuclear energy release is the process of converting nuclear energy into usable forms of energy, such as heat or electricity. This is typically done through nuclear reactions, where the nucleus of an atom is split or combined with another nucleus, releasing a large amount of energy.

2. How is nuclear energy released?

Nuclear energy is released through either nuclear fission or nuclear fusion. In nuclear fission, the nucleus of an atom is split into smaller fragments, releasing energy in the process. In nuclear fusion, the nuclei of two atoms are combined, also releasing energy.

3. What are the advantages of nuclear energy release?

Nuclear energy release has several advantages, including its high energy density, low greenhouse gas emissions, and reliability. It also does not rely on fossil fuels, making it a more sustainable option for energy production.

4. What are the risks associated with nuclear energy release?

The main risks associated with nuclear energy release include the potential for accidents, such as meltdowns, and the long-term storage of nuclear waste. There are also concerns about the environmental impacts of uranium mining and the potential for nuclear weapons proliferation.

5. How is nuclear energy release regulated?

Nuclear energy release is heavily regulated by government agencies, such as the Nuclear Regulatory Commission in the United States. These agencies set safety standards and monitor nuclear power plants to ensure they are operating safely. International organizations, such as the International Atomic Energy Agency, also play a role in regulating nuclear energy release.
