Analyzing powers for elastic and inelastic scattering of polarized 6Li from 9Be at 32 MeV

Vector and tensor analyzing powers (iT11, TT20, T20, and T22) for the 9Be(6L rvec i,6Li)9Be elastic scattering and inelastic scattering leading to the 5/2- (2.43 MeV) excited state in 9Be are presented for a 6L 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 iT11 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
