Nuclear Fission - an overview ScienceDirect Topics

Spontaneous fission gives much the same result as induced nuclear fission. However, like other forms of radioactive decay, it occurs due to quantum tunneling, without the atom having been struck by a neutron or other particle as in induced nuclear fission. Spontaneous fissions release neutrons as all fissions do, so if a critical mass is present, a spontaneous fission can initiate a self-sustaining chain reaction. Radioisotopes for which spontaneous fission is not negligible can be … WebInduced nuclear fission occurs: When a stable nucleus splits into small nuclei from the bombardment of a slow-moving neutron For example, when a uranium-235 nucleus …
