The fission barrier refers to the energy barrier that must be overcome for a nucleus to undergo nuclear fission. In the context of nuclear physics, fission occurs when a heavy nucleus splits into two or more lighter nuclei, accompanied by the release of energy, usually in the form of kinetic energy of the fission fragments and neutrons. The fission barrier can be conceptualized in terms of potential energy.
