Nuclear binding energy,Mass Defect and Binding Energy

Exercise of Nuclear reactor physics by ing. Giorgio Bertucelli.

Rest mass of some nuclear subparticles:

In a nuclear reaction we must check the following mass and charge balances:

The subject of nuclear stability will be not treated at this point; a semi-empirical approach, based on nuclear masses, will be used here.

Mass Defect and Binding Energy

Nuclear Binding Energy= the work required to disintegrate a nucleus completely into Z protons and (A-Z) neutrons.
The binding energy may be calculated from the equations:
