%X We present numerical calculations for the structure and mass of the i + nucleon in the chiral limit, using a covariant, QCD based formalism developed previously. The three-body problem of quarks interacting'via gluon exchange is treated as a quark-diquark two-body problem. The nucleon mass and a nucleon-quark-diquark form factor are determined as a function of the one parameter, the diquark form factor normalisation, which can be determined by functional methods. The constituent mass  the unpaired quark within the nucleon is estimated to be about 0.44 Gey.
