WebSome nuclides, such as 239 Pu, produce more neutrons per fission than others, such as 235 U. Additionally, some nuclides are easier to make fission than others. In particular, 235 U and 239 Pu are easier to fission than the much more abundant 238 U. Both factors affect critical mass, which is smallest for 239 Pu. WebNeutrons in the energy range 0.5–10 keV are called intermediate neutrons. These neutrons may also be called resonance or epithermal neutrons. Fast neutrons are those in the energy range 10 keV to 10 MeV.
