Noun
a constituent (proton or neutron) of an atomic nucleus
Source: WordNetAlmost all neutrons that fused instead of decaying ended up combined into helium-4, due to the fact that helium-4 has the highest binding energy per nucleon among light elements. Source: Internet
Another example is the "nucleon particle". Source: Internet
Binding energy per nucleon of common isotopes. Source: Internet
For example, the data showed that some 45% of the energy momentum was carried by electrically-neutral particles in the nucleon. Source: Internet
For heavier nuclei, the binding energy per nucleon in the nucleus begins to decrease. Source: Internet
For nucleon pairs, however, it is often energetically favorable to be at high angular momentum, even if its energy level for a single nucleon would be higher. Source: Internet
