Angular distributions of ${}^7\mathrm{Li}+{}^{11}\mathrm{B}$ elastic and inelastic scattering were measured at $E_{\mathrm{lab}}$(${}^{11}\mathrm{B}$) $=44\mathrm{MeV}$ for the transitions to the ground and excited states of ${}^7\mathrm{Li}$ and ${}^{11}\mathrm{B}$. The present data and data taken from the literature at $E_{\mathrm{lab}}$(${}^7\mathrm{Li}$) $=34\mathrm{MeV}$ were analyzed within the optical model and coupled-reaction-channels methods. Elastic and inelastic scattering, reorientations of ${}^7\mathrm{Li}$ and ${}^{11}\mathrm{B}$, and the most important one- and two-step transfers were included in the channels-coupling scheme. The dependence of the ${}^7\mathrm{Li}+{}^{11}\mathrm{B}$ optical potential on kinetic energy was taken into account. The deformation parameters of ${}^7\mathrm{Li}$ and ${}^{11}\mathrm{B}$ and optical model parameters for interaction of these nuclei in ground and excited states were deduced. The contributions of one- and two-step transfers to the elastic and inelastic scattering were estimated.
