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 moderated in a medium with a certain temperature.pithermal neutrons have energies between 1 eV and 10 keV and smaller nuclear cross sections than thermal neutrons.
The thermal neutron velocity, v T = v p, is the most probable velocity at temperature, T, and can be related to the most probable velocity at room temperature 00 2 TTvmkTv T = = (14) This expression is useful in finding the thermal neutron velocity at temperatures other than 20Â°C.By comparing Eqs.or a neutron at 20Â°C, the most probable velocity is then 2197 m/secJkg m /s(1.675 10 kg)2 (2)(1.38 10 J/ K)(273 20 K) 2 227230 ââ =â âââââ âÃÃ Â° + Â°= = ââ mkTv (6) where the zero subscript implies thermal equilibrium at this reference (room) temperature.
