Neutrons 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 ... |
The present paper deals with the epithermal neutron flux distribution in a thermal reactor. The differences are discussed between the simplified. |
The results show that neutrons above 10 keV can be useful for BNCT. The exact limit of the epithermal range depends on the location of the tumor. |
Maps of epithermal- and fast-neutron fluxes measured by Lunar Prospector were used to search for deposits enriched in hydrogen at both lunar poles. |
The very same activity that can be excited by absorption of thermal neutrons in the probe substance can also be excited by absorption of epithermal neutrons, ... |
20 авг. 2012 г. · Slow neutrons have an energy less than 1 eV. Epithermal neutrons have an energy from 0.025 to 1 eV. Hot neutrons have an energy of about .2 eV. |
