Abstract
The relativistic Faddeev equation for quarks is solved in the NJL mode l including the axial-vector diquark channel together with the scalar one. It is found that the axial-vector diquark channel contributes sig nificantly to the energy of the nucleon state. We show the region of t he effective coupling constants in the scalar and axial-vector diquark channels which give about the right nucleon mass. In particular, the color current type interaction Lagrangian gives a reasonable nucleon m ass.
