Source sentences:
text: This means that not only can it slow down neutrons to velocities in equilibrium with surrounding molecules ("thermalize" them and turn them into low-energy neutrons, known as thermal neutrons, that are far more likely to interact with the uranium-235 nuclei than the fast neutrons produced by fission initially), but it also absorbs some of them.
text: Slow neutron: A neutron produced by fission in a nuclear reactor, and slowed by a moderator.
