Fission
(gcide) | Fission \Fis"sion\, n. [L. fissio. See Fissure.]
1. A cleaving, splitting, or breaking up into parts.
[1913 Webster]
2. (Biol.) A method of asexual reproduction among the lowest
(unicellular) organisms by means of a process of
self-division, consisting of gradual division or cleavage
of the into two parts, each of which then becomes a
separate and independent organisms; as when a cell in an
animal or plant, or its germ, undergoes a spontaneous
division, and the parts again subdivide. See
Segmentation, and Cell division, under Division.
[1913 Webster]
3. (Zool.) A process by which certain coral polyps,
echinoderms, annelids, etc., spontaneously subdivide, each
individual thus forming two or more new ones. See
Strobilation.
[1913 Webster]
4. (Physics) The act or process of disintegration of an
atomic nucleus into two or more smaller pieces; called
also nuclear fission. The process may be spontaneous or
induced by capture of neutrons or other smaller nuclei,
and usually proceeds with evolution of energy.
[PJC] |
fission
(wn) | fission
n 1: reproduction of some unicellular organisms by division of
the cell into two more or less equal parts
2: a nuclear reaction in which a massive nucleus splits into

fission device
(gcide) | Nuclear device \Nu"cle*ar dev"ice\, n.
an explosive device, whether used as a weapon or for other
purposes, which depends for most of its explosive power on
the release of energy from within atomic nuclei. A {fission
device} or a fusion device.
[PJC] |
fission weapon
(gcide) | Nuclear weapon \Nu"cle*ar wea"pon\, n.
A weapon of great explosive power, such as an atomic bomb
or a hydrogen bomb, which depends for most of its explosive
power on the release of energy from within atomic nuclei by a
nuclear reaction. A fission weapon or a fusion weapon.
The term includes atomic shells for cannon.
