【 摘 要 】

We simulate quenched QCD with the overlap Dirac operator. We work with the Wilson gauge action at(beta)= 6 on an 18(sup 3) x 64 lattice. We calculate quark propagators for a single source point and quark mass ranging from am(sub 4)= 0.03 to 0.75. We present here preliminary results based on the propagators for 60 gauge field configurations.
