You were talking about protons. I can think of only two examples where the binding energy of a proton is negative. 1. Protium. 2. Helium. (There may be a few more, e.g. very neutron poor isotopes, which are radioactive to either positron decay or electron capture, with a very short half life.) > >> Besides which, you posit Coulomb force repulsion *after* strong force >attraction, but this makes no sense, because the strong force goes as the >sixth power of distance whereas the Coulomb force goes as the second power, >so once the strong force gains the upper hand, it retains control. > >Well, it makes perfect sense because the strong force is known to operate >only in one vector. Really? That's news to me. Perhaps you could provide a reference? >It is the same thing when two neutrons come together. >There is negative binding energy, and fusion cannot take place - yet the >strong force brings them together and they immediately separate - EVEN >WITHOUT COLOUMB repulsion (other than near-field). IMO there is no strong force between neutrons, nor between protons. This neatly explains why neither the dineutron not Helium2 are stable.
