  1. 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 . Nuclear fission was discovered on 19 December 1938 in Berlin by German chemists Otto Hahn and ...

  2. Nuclear fission is a kind of nuclear reaction. It is when an atom splits apart into smaller atoms. Some fission reactions give off a lot of energy, and are used in nuclear weapons and nuclear reactors. Nuclear fission was discovered in December 1938 by physicists Lise Meitner and Otto Frisch, who observed a uranium nucleus splitting in two.

  4. A nuclear fission reaction is a process that begins when a neutron or other particle strikes a nucleus. This creates fragments of the original nucleus. It also creates new neutrons that can then collide with other nuclei to cause more nuclear reactions. Infographic from the U.S. Nuclear Regulatory Commission 2018-2019 Information Digest, NUREG ...

  6. Apr 9, 2024 · 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. Nuclear fission may take place spontaneously or may be induced by the excitation of the nucleus.
