摘要：

We calculate magnetic moment and quark total angular momentum of the proton and neutron. All calculations are performed in quenched QCD formulation using Wilson fermion approach for 100 configurations. Lattice 16(3) x 32 was used for beta = 6.0. Three values of quark mass were taken: 210,124 and 80MeV. Value of the quark total angular momentum is consistent with the previous calculations. Contribution of the disconnected diagrams was studied for quark mass 210MeV using expansion technique.
