Projectile excitation and structure effects in polarized sup(6,7)Li scattering

The surprisingly large magnitude and opposite signs of the measured vector analysing powers of 6Li and 7Li elastic scattering from 58Ni at Esub(cm) approxlmately or 20MeV are nicely reproduced by coupled-channels calculations includingprojectile excitation channels. The mechanism for producing an effective spin-orbit interaction between nuclei from projectile excitation is quite general and is applicable to other scatterings. The tensor analysing power of 6Li scattering is found to be sensitive to the projectile surface structure. (author)
