Cross sections for (n,2n), (n,α), (n,p), and (n,t) reactions were measured on yttrium isotopes at neutron energies ranging from 13.5 to 14.8 MeV using the activation technique in combination with high-resolution gamma-ray spectroscopy. The monoenergetic neutron beam was produced via the 3H(d,n)4He reaction using solid T-Mo. Data are reported for the following reactions: 89Y(n,2n)88(m+g)Y, 89Y(n,α)86(m+g)Rb, 89Y(n,p)89Sr, and 89Y(n,t)87mSr. The cross sections were also estimated with the TALYS-1.8 nuclear model code using different level density options, at neutron energies varying from the reaction threshold to 20 MeV. Results are also discussed and compared to corresponding values found in the literature.
