Angular distributions for the ${}^9\mathrm{Be}({}^8\mathrm{Li},{}^9\mathrm{Be}){}^8\mathrm{Li}$ elastic-transfer reaction have been measured with a 27-MeV ${}^8\mathrm{Li}$ radioactive nuclear beam. Spectroscopic factors for the $\langle {}^9\mathrm{Be}|{}^8\mathrm{Li}+p\rangle$ bound system were obtained from the comparison between the experimental differential cross sections and finite-range distorted-wave Born approximation calculations made with the code FRESCO. The spectroscopic factors so obtained are compared with shell-model calculations and other experimental values. Using the present value for the spectroscopic factors, cross sections and reaction rates for the ${}^8\mathrm{Li}(p,\gamma ){}^9\mathrm{Be}$ direct proton-capture reaction of astrophysical interest were calculated in the framework of the potential model.
