The measurement of one-neutron stripping cross sections for the ${}^{89}\mathrm{Y}\left({}^6\mathrm{Li},{}^5\mathrm{Li}\right){}^{90}\mathrm{Y}^{*}$ reaction at 22 MeV and 34 MeV is reported, using both in-beam and off-beam $\gamma$-ray spectroscopy methods. Characteristic $\gamma$ lines of ${}^{90}\mathrm{Y}$ are clearly identified by both the $\gamma \text{−}\gamma$ and proton-$\gamma$ coincidence methods. The obtained cross section of one-neutron stripping at 34 MeV is found to be much smaller than that at 22 MeV. The one-neutron stripping cross sections measured for this system have the same order of magnitude as the one measured for the same reaction for the ${}^6\mathrm{Li}+{}^{96}\mathrm{Zr}$ system at energies around the Coulomb barrier. Parameter-free coupled reaction channel calculations agree quite well with the experimental data. Theoretical study of the effect of the one-neutron transfer on the elastic total fusion cross section is performed.
