Abstract
We solve the relativistic Faddeev equation in the Nambu-Jona-Lasinio m odel numerically in the ladder approximation. The contributions of the scalar and the axial-vector diquark channels to the nucleon state are studied. We calculate the charges and the axial coupling constants of nucleons using Faddeev wave function.
