Spontaneous fission
Spontaneous fission is a form of
radioactive decay characteristic of very heavy isotopes, and is theoretically possible for any atomic nucleus whose mass is greater than or equal to 100 amu. In practice, however, spontaneous fission is only energetically feasible for atomic masses above 230 amu.
