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?
