		Definition of slow neutron in English: slow neutronnoun A neutron with low kinetic energy especially after moderation.  Example sentencesExamples -  Much to Fermi's surprise, the slow neutrons were extremely effective in the production of nuclear reactions.
 -  The probe contains a source of fast neutrons, and the gauge monitors the flux of slow neutrons scattered by the soil.
 -  In a series of experiments, he also found that slow neutrons were efficient agents of nuclear transformations and won the Nobel Prize in Physics in 1938.
 -  The safe operation of a reactor requires that the multiplication of slow neutrons be controlled throughout the fission cycle.
 -  The first genuine transuranic element was discovered at Berkeley, where Edwin McMillan used Lawrence's cyclotron in 1939 to bombard uranium with slow neutrons.
 -  In contrast, uranium 238 has an even number of neutrons and slow neutron bombardment does not cause fission.
