摘要：

New experimental cross-section data for the W-180(n,2n)W-179m, W-186(n,2n)W-185m and W-186(n,p)Ta-186 reactions at the neutron energies of 13.5 and 14.4 MeV are obtained by the activation technique. The neutron beams are produced by means of the H-3(d,n)He-4 reaction. The gamma activities of the product nuclei are measured by a high-resolution gamma-ray spectrometer with a coaxial high-purity germanium detector. The neutron fluence is determined using the monitor reaction Nb-93(n,2n)Nb-92m. The results in the current work are discussed and compared with the measurement results found in the literature. It is shown that these higher accuracy experimental cross-section data around the neutron energy of 14 MeV agree with some previous experimental values from the literature within experimental uncertainties.
