Abstract

Description

We consider the covariant Spectator equation with a One Boson Exchange (OBE) kernel, and apply it to the NN system. Relativistic effects such as retardation and negative-energy state components are included in that equation. We develop a method, based on the Padé method, to solve the Spectator equation without partial wave decomposition. The convergence of the partial wave decomposition series is tested as a function of the energy. The on- and off-mass-shell amplitudes are calculated. The NN interaction was fitted to the differential cross section for NN scattering, in the energy range below the pion production threshold.
