Abstract：
In the Walecka model of the relativistic nucleon-meson field theory, by using the models nucleon-nucleon interaction, the optical potential (OP) in the local density approximation (LDA) is folded, so that the effect of the interaction range on the relativistic nucleon-nucleus microscopic optical potential can be discussed. With this OP, the differential cross section of the nuclear elastic scattering and spin observables are analyzed. Comparing with the result calculated in LDA, a better agreement between our result and the experimental data is obtained.
