N2 - The cross sections of 181Ta(n,p)181Hf, 181Ta(n, np>)180mHf, 184W(n,α)181Hf, 186W(n, np)185Ta and 186(n, α)183Hf reactions have been measured in the energy range between 13.4 and 14.9 MeV by the activation method. The intense 14 MeV neutron source facility (OKTAVIAN) at Osaka University was used for irradiation. The γ-rays emitted from the irradiated samples were measured with high-purity germanium (HPGe) detectors. All cross section values were obtained relative to the standard reaction cross section of 93Nb(n, 2n)92mNb obtained by Netha way. The cross sections of 181Ta(n, np)180mHf reaction were measured for the first time. The present results were compared with previous data and the evaluated data of JENDL-3 and ENDF/B-VI, and the comparison showed that some significant discrepancies exist.
