Nuclear fission - Wikipedia
WEBNuclear 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.

DOE Explains...Nuclear Fission | Department of Energy
WEBNuclear fission is the process where the nucleus of an atom splits into two or more smaller nuclei and other particles. These particles can include neutrons, alpha particles (helium nuclei), beta particles (electrons), and gamma rays (which consist of particles of light, or photons).

WEBMay 13, 2023 · In nuclear fission, the nucleus of a heavy atom, such as uranium or plutonium, splits into two or more smaller nuclei, along with a few neutrons and a significant amount of energy. Conversely, nuclear fusion involves two light elements, typically isotopes of hydrogen (deuterium and tritium), merging under conditions of extremely high ...
