What is mean by a "thermal neutron"? Question 22 options: a) a neutron with kinetic energy 1/40 of an eV b) one of the neutrons which is produced in a typical nuclear fission reaction c) a neutron inside any large nuclues d) a neutron with kinetic energy about 5 MeV
: a) a neutron with kinetic energy 1/40 of an eV .
Thermal neutrons are those which have energy about (1/40) eV or 0.025 eV. They have this name because they would be in thermal equilibrium with atoms at room temperature, 300 K. Fast neutrons are those which have energies of a few MeV, such as are produced in a fission reaction.Slow neutrons are the same as thermal neutrons.
