Fast [ edit] A fast neutron is a free neutron with a kinetic energy level close to 1 M eV (100 T J / kg ), hence a speed of 14,000 km/ s or higher. They are named fast neutrons to distinguish them from lower-energy thermal neutrons, and high-energy neutrons produced in cosmic showers or accelerators. See more The neutron detection temperature, also called the neutron energy, indicates a free neutron's kinetic energy, usually given in electron volts. The term temperature is used, since hot, thermal and cold neutrons are See more • Absorption hardening • List of particles • Neutron detection • Neutron source See more • Language of the Nucleus See more But different ranges with different names are observed in other sources.
