** Resonance with nucleus activation energies leads to preferring absorption over scattering
** Resonance with nucleus activation energies leads to preferring absorption over scattering
** Nucleon-nucleon forces are typically described in per-{isotope X fine structure} terms, ignoring hyperfine details
** Nucleon-nucleon forces are typically described in per-{isotope X fine structure} terms, ignoring hyperfine details
** Result: for a given isotope, there's a function taking {excitation level X neutron energy} to {fission probability}
* Electodynamics - strong nuclear force - weak nuclear force - quantum tunneling
* Electodynamics - strong nuclear force - weak nuclear force - quantum tunneling
** Thermal neutrons can't classically cross Coulomb repulsions, but tunneling permits π-induced fission (π = pion, aka any of 3 π-mesons)
