The authors identified eight radionuclides 196 Au, 195 Au, 194 Au, 193 Au, 192 Au, 191 Au, 190 Au, 189 Au formed via the multiple photoneutron reactions 197 Au(gama, kn)197-k Au with 2.5 Ge V bremsstrahlung. The yields of radionuclides that decay by emitting gama-ray were measured using high purity germanium (HPGe) detector coupled to a PC-based multichannel analyzer. In order to improve the accuracy of the experimental results the necessary corrections were made. The obtained results are compared with reference data and the variations of the 197 Au(gama,kn/)197-k Au reaction yields according to incident bremsstrahlung energy and neutron multiplicity are also discussed.
