Slow neutrons: Neutrons in a nuclear reactor slowed down by repeated collisions with core material to a speed comparable with that of gaseous molecules.
Notes :
Slow neutrons are far more likely to occasion a fission on colliding with a fissile nucleus and fast neutrons are purposely slowed down by moderator material to increase the probability of such fissions taking place.
