Nuclear fission is a process in which a heavy atomic nucleus splits into two more-or-less equal fragments accompanied by the release
of large amounts of energy. A chain reaction results when the neutrons released during
fission cause other nearby nuclei to break apart. Fission may occur spontaneously
or may be induced by capture of bombarding particles. In addition to the
fission fragments, neutrons and gamma rays are usually produced during fission.
