Nuclear binding energy ($E_{\mathrm{bind}}=(Z{m}_p+N{m}_n-M_A)c^2$)

The positive energy needed to separate a bound atomic nucleus into its constituent protons and neutrons. It is the mass defect times $c^2$. In a Skyrmion model of a nucleus, both separated nucleon masses and the multi-soliton state require a consistent quantization and calibration.
