Abstract

A complete set of analyzing powers has been obtained for 12C(7Li,7Li)12C elastic scattering at a bombarding energy of 34 MeV. Optical model calculations using standard forms for the spin-orbit and tensor potentials are unable to simultaneously describe all the available data. However, coupled-discretized-continuum-channels (CDCC) calculations using cluster-folding model form factors provide a reasonable overall description of the data with only two adjustable parameters. Reorientation effects are extremely important in obtaining a good description of the analyzing powers, with the reorientation coupling of the 7Li ground state being a major contributor to all the analyzing powers and the main source of the second-rank tensor analyzing powers T20, T21, and T22. The failure of optical model calculations to describe the second rank data implies that the effect of this reorientation coupling cannot be described accurately by means of a dynamic polarization potential constrained to be of the standard forms. The CDCC calculations also demonstrate the effect of coupling to the αt continuum on the analyzing powers.
