Abstract: Measurements of 176Hf(n, 2n)175Hf cross sections were carried out in the range of 13.4-14.8 MeV using the activation method and relative measurement technology. The samples were irradiated at the various positions on the ring of a 20 cm radius centered at the D-T neutron source. The 93Nb(n, 2n)92Nbm reaction was used to monitor the neutron flux in the target samples. The (n, 2n) products were measured using calibrated high pure Ge detector. 176Hf(n, 2n)175Hf cross section is (2 100±85) mb at 14 MeV. The results were presented and compared with the references’ results and ENDF/B6.8 evaluations.
