# 'Forces' enacted by hot neutrons in fusion bomb - Pauli exclusion

Are Pauli exclusion 'forces' on a neutron 100% electromagnetic (Lennard-Jones seems more acute relationship compared to electrostatic force) If so does that neutrons have two forces between them - 'electrodynamic' repulsion and the strong meson attraction? Thus, in nuclear fusion bombs, I read the neutrons initiate fusion on Lithium deuteride by collision. Is this by Pauli/ED forces, mesons/strong force or both?

• The neutron can cause the Li6(n,T)$\alpha$ reaction, making tritium that could then fuse with deuterium. – Jon Custer Jan 11 at 14:51
• Is the usefulness of neutrons in fusion in a very specific reaction/ one-trick pony? I wondered why they don't use lasers to create 'hot' neutrons to bombard fusion fuel? I see some Japanese scientists are accelerating electrons with lasers. Is it easier/more efficient to accelerate an electron than a neutron with a laser and are electrons more likely to raise the temperature? – JKB Jan 17 at 10:37
