We discuss density of states of a hole doped into a spin-1 / 2 Heisenberg antifer-romagnet (AF). From the multi-spin correlation functions, moments of the density ofstates are estimated up to the 8-th order taking into account the effect of local spinrelaxation around a hole. We show the density of states for AF shows divergentbehavior near the band edge.[spin wave approximation, Heisenberg antiferromagnet, oxide superconductiv- lJ ity, hole doping, spin defect, density of states, theoryl
