(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 process whereby one item splits to become two. (physics): The process of splitting an atom into smaller particles. (biology): The process by which a bacterium splits to form two daughter cells.

The splitting of the nucleus of an atom (generally of a heavy element) into at least two other nuclei and the release of a relatively large amount of energy. Two or three neutrons are usually released [..]

the splitting of a nucleus into at least two other nuclei that releases a large amount of energy. Two or three neutrons are usually released during this transformation. See also fusion.

Is a nuclear process in which a heavier unstable nucleus divides or splits into two or more lighter nuclei, with the release of substantial amounts of energy. When a free neutron of the proper energy is captured by the nucleus of a fissionable atom, the resulting unstable nucleus will split producing two or more fission products (atomic nuclei of d [..]
