| fission |
a process, which, along with fusion, releases energy stored in separated nuclei. During fission, a fissionable nucleus such as plutonium absorbs a neutron, becomes unstable and splits into two nuclei, releasing energy. Nuclear power is a controlled, self-sustaining fission process; nuclear explosions are an uncontained chain reaction version of the fission process. ...

| fission |
The splitting of a heavy nucleus into two or more radioactive nuclei, accompanied by the emission of gamma rays, neutrons and a significant amount of energy. Fission usually is initiated by the heavy nucleus absorbing a neutron, but it also can occur spontaneously.

| fission |
The splitting of the nucleus of an atom into nuclei of lighter atoms, accompanied by the release of energy. This can be a spontaneous event or can be stimulated by the bombardment of a target nucleus with subatomic particles like protons or neutrons.
