  • n. The act or process of splitting into parts.
  • n. A nuclear reaction in which an atomic nucleus, especially a heavy nucleus such as an isotope of uranium, splits into fragments, usually two fragments of comparable mass, releasing from 100 million to several hundred million electron volts of energy.
  • n. Biology An asexual reproductive process in which a unicellular organism divides into two or more independently maturing daughter cells.
  • v. To cause (an atom) to undergo fission.

See Segmentation, and Cell division, under Division.

  • n. 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.
    • The Century Dictionary and Cyclopedia
  • n. The act of cleaving, splitting, or breaking up into parts.
  • n. In biology, the automatic division of a cell or an independent organism into new cells or organisms; especially, such division as a process of multiplication or reproduction. Also fissuration. See cut under Paramecium.
