Induced nuclear fission occurs when a particle — commonly a neutron — passes a large target atomic nucleus ... If less than one neutron from a fission reaction causes a further ...

Chi-Nu focuses on "fast-neutron-induced" fission, with incident neutron energies in millions of electron volts, where there have typically been very few measurements.

In small reactors, however, the spontaneous (that is, not induced by neutrons) fission of radioactive nuclei such as uranium-238 prevents a complete die-off, since spontaneous fission also creates ...

Nuclear fission—when the nucleus of an atom splits in two, releasing energy—may seem like a process that is fully understood. First discovered in 1939 and thoroughly studied ever since ...

Based on studying the prompt fission neutron spectrum of the induced fission of plutonium-240, researchers at LANSCE have found discrepancies with nuclear data libraries, especially on the energy ...

The research team investigated the fission properties of 100 different neutron-deficient exotic isotopes, ranging from iridium (atomic number Z = 77) to thorium (Z = 90).

Neutron stars and nuclear fission . Neutron stars are created when massive stars reach the end of their fuel supplies necessary for intrinsic nuclear fusion processes, which means the energy that ...

In their recent study published in Physical Review C, the team explored the possible emission rate of particle-stable tetraneutron via thermal neutron-induced fission of 235 U (Uranium-235) in a ...

This fission occurs when atomic nuclei grab free neutrons and form heavy, but unstable, elements. When it comes to nuclear energy , human engineering and the rest of the universe are a bit at odds.

Article Title. Measurement of the 238U(n, f) prompt fission neutron spectrum from 10 keV to 10 MeV induced by neutrons with 1.5–20 MeV energy ...
