These and neutrons

These delayed neutrons, which are emitted at lower velocities, will limit the rate at which a nuclear reactor will shut down.
These TRIUMF facilities, PIF & NIF, have since become recognized as premier test sites for space-radiation effects using protons and, with the capability of using these protons to produce a neutron-energy spectrum similar to that found at aircraft altitudes and at ground level, testing with neutrons is also possible.
These fission products are important to the operation of the reactor because some fission products contribute delayed neutrons that are useful for reactor control while others are neutron poisons that tend to inhibit the nuclear reaction.
These neutrons can be used to produce extra fuel, or to transmute long half-life waste to less troublesome isotopes, such as was done at the Phénix reactor in Marcoule in France, or some can be used for each purpose.

These are small particle accelerators that cause a brief fusion reaction by accelerating deuterium into a tritium target ( or potentially vice-versa ), producing a short energetic pulse of neutrons.
These correspond to the cohesive binding of all the nucleons by the strong nuclear force, the electrostatic mutual repulsion of the protons, a surface energy term, an asymmetry term ( derivable from the protons and neutrons occupying independent quantum momentum states ) and a pairing term ( partly derivable from the protons and neutrons occupying independent quantum spin states ).
