A relativistic nuclear mean field model is developed involving nucleons coupled to effective scalar and vector fields. It differs slightly from the usual Walecka model in the form of the coupling of the nucleon to the scalar meson. We calculate the equation of state for symmetric nuclear matter at zero temperature. The model, which has no arbitrary parameters, once we fit the empirical density and energy of nuclear matter, yields a compression modulus of 225 MeV and an effective nucleon mass=0.85.
