New measured results were obtained for the (58)Ni(n,p)(58)Co, (58)Ni(n,2n)(57)Ni, (58)Ni(n,x)(57)Co, (60)Ni(n,p)(60)Co, (59)Co(n,2n)(58)Co, (59)Co(n,p)(59)Fe, (63)Cu(n,alpha)(60)Co, (204)Pb(n,n')(204 m)Pb and (204)Pb(n,2n)(203)Pb reaction cross-sections. These reactions may be of interest for dosimetry. Measurements were taken at the 7 MV Van de Graaff accelerator at IRMM, Geel, using the activation technique in combination with high-resolution gamma ray spectrometry. The present results are compared with other measurements, evaluated data and model calculations.
