In the fermigas model protons are stronger bound than neutrons due to coulomb repulsion. Why does the illustration above show Sp on a lower energy level than Sn as this would mean there has to be more energy added to free the proton from the nucleus and thus is stronger bound. Is this illustration in my textbook wrong or am I missing something?
