Abstract  By introducing the double spacetime manifold, the double gamma matrices and Dirac spinors, the action of the Dirac spinoral fields is doubled. Furthermore, the double coupling of the Dirac fields to the Ashtekar gravitational fields is studied.
Keywords:  Ashtekar gravitational theory      Dirac spinoral fields      Hamiltonian constraint equations
