Abstract
Vector and tensor analyzing powers (,,, and ) for Li→LiC elastic scattering and inelastic scattering leading to the (4.44 MeV) and (9.64 MeV) states in are presented over the c.m. angular range 15–138° for a bombarding energy of 30 MeV. These are the first complete set of analyzing powers for scattering. The results of a coupled channels analysis that uses an optical potential with a double-folded real part show the necessity to include projectile excitation, an explicit spin-orbit potential, and reorientation terms in the potential in order to achieve a reasonable overall description of the analyzing-power data. The deformation lengths are set by normalizing the calculations to previously measured (,) inelastic-scattering cross sections. The explicit spin-orbit potential is the major contributor to the vector analyzing power for () inelastic scattering, while the reorientation of the ground state contributes strongly to the analyzing power for elastic scattering. The calculations fail to account for the relatively large magnitude of the experimental tensor analyzing powers for the () inelastic scattering.
