Cross sections for $(n,2n)$, $(n,p)$, $(n,n^{\text{'}}\alpha )$, $(n,t)$, $(n,d^{\text{'}})$, and $(n,\alpha )$ reactions have been measured on tantalum isotopes at the neutron energies of 13.5 to 14.7 MeV using the activation technique. Data are reported for the following reactions: ${}^{181}\mathrm{Ta}(n,2n){}^{180}\mathrm{Ta}{}^g$, ${}^{181}\mathrm{Ta}(n,p){}^{181}\mathrm{Hf}$, ${}^{181}\mathrm{Ta}(n,n^{\text{'}}\alpha ){}^{177}\mathrm{Lu}{}^m$, ${}^{181}\mathrm{Ta}(n,t){}^{179}\mathrm{Hf}{}^{m2}$, ${}^{181}\mathrm{Ta}(n,d^{\text{'}}){}^{180}\mathrm{Hf}{}^m$, and ${}^{181}\mathrm{Ta}(n,\alpha ){}^{178}\mathrm{Lu}{}^m$. The neutron fluences were determined using the monitor reaction ${}^{27}\mathrm{Al}(n,\alpha ){}^{24}\mathrm{Na}$. Results were discussed and compared with the previous works.
