← ScienceWhich outcome occurs in neutron moderators using deuterium isotopes?
A)Reduced neutron kinetic energy✓
B)Increased rate of fission
C)Enhanced gamma ray production
D)Isotope transmutation to tritium
💡 Explanation
Neutron moderators slow neutrons via inelastic scattering. Because deuterium offers a close mass match with bombarding neutrons, energy transfer is maximized via kinetic energy loss rather than nuclear fusion; therefore, neutron kinetic energy decreases and chain reactions are sustained.
