Binding Energy vs Mass Defect
Nuclear Binding Energy
Binding energy is the energy required to disassemble a nucleus into free protons and neutrons.
Formula
E = delta_m * c²
Using atomic mass units: E (MeV) = delta_m (u) * 931.494 MeV/u
The mass defect delta_m is the difference between the sum of individual nucleon masses and the actual nuclear mass.
Example Calculation
Helium-4 nucleus with mass defect 0.03437 u.
- 01E = delta_m * 931.494 MeV/u
- 02E = 0.03437 * 931.494
- 03E = 32.02 MeV
- 04E per nucleon = 32.02 / 4 = 8.005 MeV/nucleon
