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 nd 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 for 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}{sup 5} coupling for the pion, and a second with 6 mesons ({pi}, {sigma}, {rho}, {omega}, {delta}, and {eta}) but a pure {gamma}{sup 5}{gamma}{sup mu} 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 {rho} {sup 40}C{alpha} elastic scattering observables. 19 refs., 6 figs., 1 tab.
