摘要：

Quenched QCD hadron spectrum is calculated with Wilson's quark action at beta = 5.85 and 6.0 on a 24(3) x 54 lattice. We discuss the problem of whether we have extracted the mass of the ground state at these beta's without contamination of the excited states. We show that the masses of the first excited states turn out to be consistent with experiment when we are able to obtain the propagators up to the large time slice region where the propagators take the asymptotic forms of the ground states.
