Relativistic Nuclear Physics with the Spectator Model
The spectator model, a general approach to the relativistic treatment of nuclear physics problems in which spectators to nuclear interactions are put on their mass-shell, will be defined and described.The approach grows out of the relativistic treatment of two and three body systems in which one particle is off-shell, and recent numerical results of the NN interaction will be presented.Two meson-exchange models, one with only 4 mesons (pi, sigma, rho, omega) but with a 25% admixture of gamma^5 coupling for the pion, and a second with 6 mesons (pi, sigma, rho, omega, delta, and eta) but a pure gamma^5 gamma^micro pion coupling, are shown to give very good quantitative fits to NN scattering phase shifts below 400 MeV, and also a good description of the p^40Ca elastic scattering observables.
