Analyzing powers for elastic and inelastic scattering of polarized Li6 from Be9 at 32 MeV

Vector and tensor analyzing powers (iT11, TT20, T20, and T22) for the Be9(6Li→,6Li)9Be elastic scattering and inelastic scattering leading to the 5/2- (2.43 MeV) excited state in Be9 are presented for a →6 bombarding energy of 32 MeV over the c.m. angular range 13°-87°. 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.
