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 ...

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 ...

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 ...

IN nuclear transformations initiated by deuteron impact, two types of processes are, as well known, to be taken into consideration. In the process of the first type (process I), the intermediate ...

Neutron-induced fission cross section of 234U and 237Np measured at the CERN Neutron Time-of-Flight (n_TOF) facility, Phys. Rev. C82, 034601. Country/Organization ...

At high enough densities, this chain reaction of neutron-induced fission can produce a nuclear explosion. In a nuclear reactor, the fuel density is low enough that this isn't a threat, ...

May 14, 2025 — An international team of scientists has identified an unexpected region of heavy, neutron-deficient isotopes in the nuclear chart where nuclear fission is predominantly governed ...

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 ...

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 ...

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.
