WebWe have already attributed the isospin projections to quarks, Eq. , by placing within the quark iso-spinor the quark up up and the ... Second, the third term in Eq. gives the coupling of nucleons to mesons, and in the potential approximation it yields the long-distance, low-energy tail of the nucleon-nucleon interaction, i.e., the ... WebThe strong interaction between any pair of nucleons is the same, independent of whether they are interacting as neutrons or as protons. Instead of regarding protons and neutrons as totally different species, as far as strong interactions are concerned, they are regarded as different isospin states of the same underlying nucleon particle.
WebSome basic features emerging from low-energy nucleon-nucleon scattering are: • the interaction has a short range of about 1 fm, • within this range, it is attractive with a depth of about 40 MeV for the larger distances, whereas • there is strong repulsion at shorter distances . 0.5 fm; • it depends both on spin and isospin of the two nucleons.
