ANALYZING POWERS FOR ELASTIC AND INELASTIC-SCATTERING OF POLARIZED LI-6 FROM BE-9 AT 32 MEV

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