Spin-Orbit Interaction Induced by Heavy-Ion Projectile Excitation

Abstract

It is shown that, for heavy-ion projectiles with a cluster structure, effects due to projectile excitation generate a large effective spin-orbit interaction which can drastically alter the predictions for vector analyzing powers obtained from folding model spin-orbit potentials. Coupled-channels calculations of this effect for ${}_{}{}^6{}_{}{}^{}\mathrm{Li}$ and ${}_{}{}^7{}_{}{}^{}\mathrm{Li}$ scattering from ${}_{}{}^{58}{}_{}{}^{}\mathrm{Ni}$ at $E_{\mathrm{c}.\mathrm{m}.\mathrm{}}\sim 20$ MeV give a good account of experimental data.
