Vector and tensor analyzing powers (${\mathit{iT}}_{11}$, ${}_{}{}^{\mathit{T}}{}_{}{}^{}$${\mathit{T}}_{20}$, ${\mathit{T}}_{20}$, and ${\mathit{T}}_{22}$) for the ${}_{}{}^9{}_{}{}^{}\mathrm{Be}$${(}^6$Li→${,}^6$He${)}^9$B reaction are presented for a ${}_{}{}^6{}_{}{}^{}\to$ bombarding energy of 32 MeV over the angular range from 14° to 80° c.m. A one-step reaction calculation is consistent with the angular distribution and vector analyzing power ${\mathit{iT}}_{11}$ for the ground-state transition but does not describe the tensor analyzing power ${}_{}{}^{\mathit{T}}{}_{}{}^{}$${\mathit{T}}_{20}$. Coupled channels calculations that include inelastic coupling in the entrance and exit channels do not reproduce either the vector or tensor analyzing powers. Sequential transfer calculations via ${(}^6$Li${,}^7$Li)${(}^7$Li${,}^6$He) do not reproduce the ground-state angular distribution but do reproduce the analyzing powers. The analyzing power data to the ${}_{}{}^9{}_{}{}^{}\mathrm{B}$(5/$2^{\mathrm{-}}$, 2.36 MeV state) are well reproduced by the coupled channels calculation although the cross section is under predicted by a factor of 3.
