1 a nuclear reaction in which a massive nucleus splits into smaller nuclei with the simultaneous release of energy [syn: nuclear fission]
2 reproduction of some unicellular organisms by division of the cell into two more or less equal parts
process whereby one item splits to become two
process of splitting an atom
- To cause to fission.
- To undergo fission.
Fission is a splitting of something into its parts.
Fission may refer to:
- In physics, nuclear fission is a process where a large atomic nucleus (such as uranium) is split into two smaller nuclei
- In biology, binary fission is the mitosis process whereby a prokaryote reproduces by cell division
- In anthropology, fission is the process whereby a nation-state divides and becomes multiple states
- In geology, fissility is the property of mudstones to split along layers
- Fission (band), a Swedish melodic death metal band
fission in Danish: Fission (flertydig)
fission in Swedish: Fission
fission in Lithuanian: Skilimas
