When a fast neutron collides with a lightnucleus, it loses a large fraction of its energy. From Wikipedia This example is from Wikipedia and may be reused under a CC BY-SA license. Its size would be a minimum of a few femtometers across (with the mass of a lightnucleus). From Wikipedia This example is from Wikipedia and may be reused under a CC BY-SA license. Ternary fission, about 0.2% to 0.4% of fissions, also produces a third lightnucleus such as helium-4 (90%) or tritium (7%). From Wikipedia This example is from Wikipedia and may be reused under a CC BY-SA license. Although it is unusually neutron-rich for such a lightnucleus, the only radioactive decay pathway open to it is the extremely rare process of double beta decay. From Wikipedia This example is from Wikipedia and may be reused under a CC BY-SA license. Eveneven nuclei are described as being composed of clusters of alpha particles, as has often been done for light nuclei. From Wikipedia This example is from Wikipedia and may be reused under a CC BY-SA license. This process takes light nuclei and forms a heavier one, through a nuclear reaction. From Wikipedia This example is from Wikipedia and may be reused under a CC BY-SA license. This is roughly 1 for light nuclei, but for heavy nuclei the ratio grows in good agreement with nature. From Wikipedia This example is from Wikipedia and may be reused under a CC BY-SA license. Kinematically, a neutron can transfer more energy to light nuclei such as hydrogen or helium than to heavier nuclei. From Wikipedia This example is from Wikipedia and may be reused under a CC BY-SA license. It is also possible that heavy element cores, such as iron, simply sink beneath the surface, leaving only light nuclei like helium and hydrogen cores. From Wikipedia This example is from Wikipedia and may be reused under a CC BY-SA license. It is used as a neutron moderator in nuclear reactors because light nuclei are more effective at slowing down neutrons than heavy nuclei. From Wikipedia This example is from Wikipedia and may be reused under a CC BY-SA license. A light substrate (light nuclei) will reduce backscattering. From Wikipedia This example is from Wikipedia and may be reused under a CC BY-SA license. For light nuclei with total nucleon numbers 1 to 6 only those with 5 do not show some evidence of stability. From Wikipedia This example is from Wikipedia and may be reused under a CC BY-SA license. If new binding energy is available when light nuclei fuse, or when heavy nuclei split, either of these processes result in releases of the binding energy. From Wikipedia This example is from Wikipedia and may be reused under a CC BY-SA license. Observations of beta-stability of light nuclei outside closed shells indicate that nuclear stability is much more complex than simple closure of shell orbitals with magic numbers of protons and neutrons.
