Fusion of two neutrons

[j2mhall]

TL;DR Summary

is it possible to get two neutrons to fuse togther to form an element?

Hi
Is it possible to get two neutrons to fuse together to form helium? If so, would it not make cold fusion possible?

 

[j2mhall]

also wouldn't fusion be much more efficient if they found a catalyst?

No. Helium already has two neutrons. You're short two protons.

I have no idea of the cross section, but it seems 2 neutrons could react to produce a deuteron, electron, and anti-neutrino with a very small release of energy.

[edit: found a paper on this: https://arxiv.org/abs/nucl-th/0507048 , published in Physics Letters B

This practical gist of this paper is that neutron fusion is unlikely to observed at all, in the near future. The computed cross section for the reaction is:

σ = (38.6 ± 1.5) × 10−40 [cm2]

changing the subject. If photons cause electrons to be removed from an atom and grativitons do the same then wouldn't a way to produce anti gravity be to remove all the electrons from an atom so that gravitons don't get absorbed?

You seem to be hijacking your own thread. But your question does not even make sense, much less have an answer.

And with that bit of wild speculation, this thread is now closed. Thank you everybody for trying to help the OP understand the issues with his question in his thread start.
