The rest mass of a stable nucleus is always less than the sum of rest masses of it's constituents and the difference is called the mass defect Δm.
Δmc2 is used in keeping nucleons bounded.
This is called binding energy.
Nuclear fission is a nuclear reaction in which the nucleus of heavy atoms splits into two or more lighter nuclei. This fission process oftenly produces gamma photons.
