Principles of Nuclear Fission

Principles of Nuclear Fission

In general, the neutron-induced fission reaction is the reaction in which the incident neutron enters the heavy target nucleus (fissionable nucleus), forming a compound nucleus that is excited to such a high energy level (Eexcitation > Ecritical) that the nucleus splits into two large fission fragments. A large amount of energy is released in the form of radiation and fragment kinetic energy.

To understand the process of fission, we must understand processes that occur inside the nucleus to be fissioned. At first, the nuclear binding energy must be defined.
