【正】 The cross sections for the <sup>165</sup>Ho(n.γ)<sup>166</sup>Ho<sup>?</sup> reaction have been measured rel-ative to the <sup>197</sup>Au(n.γ)<sup>198</sup>Au reaction at neutron energies of 203,676 and 974 keV usingthe activation technique in combination With high resolution HPGe detector gamma rayspectroscopy Experimental data were given for the first time.
