The 146 pages that link to Nuclear fission, each with the reason it gives.

• Radioactive decayCompared with: Fission is commonly induced by neutron absorption, unlike spontaneous radioactive decay.

• CombustionCompared with: It releases energy through nuclear changes rather than chemical oxidation.

• Nuclear shell modelRelated: Shell effects in fissioning nuclei helped show that nuclear energy depends on level structure.

• Manhattan ProjectNarrower topic: Fission supplied the energy release that made the project’s weapons possible.

• Nuclear fusionCompared with: Fission releases energy by splitting heavy nuclei, whereas fusion combines light ones.

• NeutronRelated: Neutrons can initiate fission and the released neutrons can sustain a chain reaction.

• Island of stabilityRelated: Shell effects can raise barriers against fission, one route by which superheavy nuclei decay.

• Nuclear binding energyRelated: Fission can release energy when its products have greater binding energy per nucleon.

• Nuclear reactorRelated: Fission releases the heat and neutrons that sustain most power reactors.

• Nuclear stabilityBroader topic: Fission is a major route by which very heavy nuclei reach lower-energy configurations.

• Atomic bombings of Hiroshima and NagasakiNarrower topic: Both bombs released energy through chain reactions involving nuclear fission.

• Atomic nucleusRelated: It is a major pathway by which nuclear binding energy becomes available.

• Ernest RutherfordRelated: Rutherford’s nuclear science preceded the later discovery of fission and its technological consequences.

• Nuclear weaponRelated: It supplies the explosive energy in fission weapons and many thermonuclear designs.

• Nuclear powerBroader topic: Fission releases the heat that most nuclear power plants convert into electricity.

• Nuclear reactionBroader topic: Fission releases energy and can sustain a neutron-driven chain reaction.

• Enrico FermiRelated: Fission supplied the neutrons and energy that made Chicago Pile-1 self-sustaining.

• Superheavy element synthesisCompared with: Fission competes with survival after fusion and destroys many candidate superheavy nuclei.

• Heavy-ion fusionCompared with: An excited fusion product may fission instead of surviving as an evaporation residue.

• Extended periodic tableRelated: Fission competes with survival in the nuclei proposed for the table’s far end.

• Werner HeisenbergRelated: Fission made Heisenberg’s wartime nuclear research consequential, though Germany did not build an atomic bomb.

• Mass–energy equivalenceRelated: The products have slightly less mass than the initial nucleus; the difference emerges as energy.

• RadioactivityRelated: Fission creates radioactive products and can sustain a chain reaction.

• ActinideRelated: Some actinide isotopes can fission, linking their nuclear structure to energy production and weapons.
