${\mathrm{The}}^{10}$B${(}^7$Li,${\mathrm{}}^7$Be${)}^{10}$Be charge-exchange reaction has been measured at $E_{\mathrm{lab}=39\mathrm{}}$ MeV. Calculations were performed using a microscopic distorted-wave Born approximation with both central and tensor forces with an optical model potential obtained by fitting measured elastic scattering data. Several residual two-body interactions were used for which the absolute cross-section magnitudes varied at most within factors of two. The calculations showed that the one-step mechanism is very important for this particular reaction even at this low bombarding energy.
