Nuclear fission - Wikipedia
Nuclear fission is a reaction in which the nucleus of an atom splits into two or more smaller nuclei. The fission process often produces gamma photons, and releases a very large amount of energy even by the energetic standards of radioactive decay.
The Fission Process | MIT Nuclear Reactor Laboratory
The arrangement of particles within uranium-235 is somewhat unstable and the nucleus can disintegrate if it is excited by an outside source. When a U-235 nucleus absorbs an extra neutron, it quickly breaks into two parts. This process is known as fission (see diagram below).
What is Nuclear Fission - Definition, Examples, Difference …
Nuclear fission is defined as the splitting of a heavier nucleus into two daughter nuclei. Learn what is nuclear fission, nuclear energy, and the difference between fission v/s fusion along with examples at BYJU’S.

Neutron-induced nuclear fission is the process of the most significant practical importance in reactor physics. Some nuclei can undergo fission on their own spontaneously, but only specific nuclei, like uranium-235, uranium-233, and plutonium-239, can sustain a fission chain reaction.
DOE Explains...Nuclear Fission | Department of Energy
Nuclear reactors can use the fission of uranium for fuel. A uranium fuel pellet the size of an egg has as much energy as 88 tons of coal. Learn more about how fission makes smoke detectors work.

2024年11月5日 · nuclear fission, subdivision of a heavy atomic nucleus, such as that of uranium or plutonium, into two fragments of roughly equal mass. The process is accompanied by the release of a large amount of energy.
What is nuclear fission? | Space
2022年9月21日 · Nuclear fission is the process of breaking large atomic nuclei into smaller atomic nuclei to release a large amount of energy. This process is usually done by forcing the nuclei to absorb...
10.6: Fission - Physics LibreTexts
Fission of a given nuclide, such as \(^{238}U\), does not always produce the same products. Fission is a statistical process in which an entire range of products are produced with various probabilities. Most fission produces neutrons, although the number varies.

2024年11月5日 · Fission Sequence of events in the fission of a uranium nucleus by a neutron. A pictorial representation of the sequence of events in the fission of a heavy nucleus is given in Figure 3. The approximate time elapse between stages of the process is indicated at the bottom of the Figure. The phenomenology of fission.
Fundamentals of the fission process - Encyclopedia Britannica
2024年11月5日 · Fission can be induced by exciting the nucleus to an energy equal to or greater than that of the barrier. This can be done by gamma-ray excitation (photofission) or through excitation of the nucleus by the capture of a neutron, proton, or …
