Vector and tensor analyzing powers ([ital iT][sub 11], [sup [ital T]T][sub 20], [ital T][sub 20], and [ital T][sub 22]) for the [sup 9]Be([sup 6]L[rvec i],[sup 6]Li)[sup 9]Be elastic scattering and inelastic scattering leading to the 5/2[sup [minus]] (2.43 MeV) excited state in [sup 9]Be are presented for a [sup 6]L[rvec i] bombarding energy of 32 MeV over the c.m. angular range 13[degree]--87[degree]. The results of coupled-channels calculations show that the relatively large observed values of the vector analyzing power [ital iT][sub 11] for the inelastic scattering can only be accounted for by an explicit spin-orbit term in the optical potential. For the elastic scattering, the vector analyzing power and the relatively small tensor analyzing powers are described reasonably well by coupled-channels calculations with no explicit spin-orbit or tensor terms in the interaction, and provide a severe constraint on the coupled-channels calculations, with a preference for an optical potential with a double-folded rather than a Woods-Saxon real part.
