Angular distributions for the ${}_{}{}^9{}_{}{}^{}\mathrm{Be}$${(}^6$Li${,}^6$He) charge exchange reaction, ${}_{}{}^9{}_{}{}^{}\mathrm{Be}$${(}^6$Li${,}^6$Li) elastic and inelastic scattering, and the ${}_{}{}^9{}_{}{}^{}\mathrm{Be}$${(}^6$Li${,}^7$Li) transfer reaction have been measured at E=32 MeV. Limited measurements at 36 MeV showed no change in the cross sections at this energy compared with those at 32 MeV. Coupled channels calculations are necessary to describe the inelastic scattering data to the ${}_{}{}^9{}_{}{}^{}\mathrm{Be}$, 2.43 MeV, ${\mathrm{}(5/2)\mathrm{}}^{\mathrm{-}}$ state. The deformation length obtained is in good agreement with the electron scattering value. A microscopic analysis of the charge exchange reaction shows that the M3Y interaction gives a good description of the ${}_{}{}^9{}_{}{}^{}\mathrm{Be}$ ground state to ${}_{}{}^9{}_{}{}^{}\mathrm{B}$ ground state transition, but underpredicts the cross section to the ${}_{}{}^9{}_{}{}^{}\mathrm{B}$, 2.36 MeV, ${\mathrm{}(5/2)\mathrm{}}^{\mathrm{-}}$ state by a factor of 3. The same calculations carried out for previously reported ${}_{}{}^{14}{}_{}{}^{}\mathrm{C}$${(}^6$Li${,}^6$He) data reproduce the magnitude of the data provided that Visscher-Ferrell densities are used for the ${}_{}{}^{14}{}_{}{}^{}\mathrm{C}$ to ${}_{}{}^{14}{}_{}{}^{}\mathrm{N}$ transition. The results of finite range distorted-wave Born approximation calculations for ${}_{}{}^9{}_{}{}^{}\mathrm{Be}$${(}^6$Li${,}^7$${\mathrm{Li}}_0$,1) ${}_{}{}^8{}_{}{}^{}$${\mathrm{Be}}_0$ show the neutron pickup spectroscopic factors to be in good agreement with the Cohen-Kurath calculations.
