Abstract
The application of a model based on lattice-gauge considerations of multiquark interactions to the nucleon-nucleon system is given. The model is a nonrelativistic Born-Oppenheimer approach which includes a confinement mechanism consistent with the local gauge invariance required by QCD. Inclusion of a one-pion-exchange interaction between quarks and a linkage exchange term as suggested in the preceding paper gives a four-parameter model which yields a remarkably good fit to low-energy neutron-proton phase shifts and the static properties of the deuteron. The results overall are similar to those obtained by phenomenological potentials based on conventional meson-exchange ideas such as the Paris potential. The parameters of this model for the nucleon-nucleon system are consistent with the parameters needed to describe the internal excitations of nucleons.
