Abstract New experimental cross-section data for the $^{180}$W(n,2n)$^{179{\rm m}}$W, $^{186}$W(n,2n)$^{185{\rm m}}$W and $^{186}$W(n,p)$^{186}$Ta 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 $^{3}$H(d,n)$^{4}$He 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 $^{93}$Nb(n,2n)$^{92{\rm m}}$Nb. 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.
