Facets:
Source sentences:
text: The stability of neutrons within nuclei is explained by the energies which would be involved in the decay of a neutron which is spin paired with a proton.
text: There is no place for this energy to come from so a neutron paired with a proton would be stable.
text: But where a neutron is paired with a proton its decay is not energy feasible and thus such neutrons within nuclei are stable.
