5. Fission
   (Nuclear) Fission is the process where a heavy nuclei (e.g. U-235) decays by splitting into two equal fragments (fission fragments). This process proceeds with the emission of Neutrons and Gamma Rays , the neutrons being available to initiated further fissions and thus a nuclear chain reaction. Some...

8. Fission
   The splitting of a heavy nucleus into two, accompanied by the release of a relatively large amount of energy and usually one or more neutrons. It may be spontaneous but usually is due to a nucleus absorbing a neutron and thus becoming unstable

11. fission
    The splitting of an atomic nucleus.This is what is done in nuclear reactors. A neutron is absorbed by the nucleus (making the nucleus unstable) which then splits into two smaller nuclei. For nuclei larger than iron, this process releases energy.

    In physics, the splitting of a heavy atomic nucleus into two or more major fragments. It is accompanied by the emission of two or three neutrons and the release of large amounts of nuclear energy.
