“…The central ingredients of the semiclassical picture are as follows [5][6][7]. The central nuclear and Coulomb interactions determine classical trajectories along which transitions between spin substates and projectile states of various energies are calculated.…”

Abstract. Experimental results of the 1st rank analyzing power for elastic scattering of 6Li and 7Li could be only understood when including coupling to inelastic channels in the calculations. This finding -established for some time -yet presents some open questions regarding the energy dependence of the spin and polarization effects. Semiclassical calculations presented here might clarify the relevant physical background of the earlier quantummechanically exact results.

A semiclassical theory for heavy ion scattering in the Fresnel diffrwtion regime cowring coupled elastic and inelastic channels is developed. The scattering is described ils diffraction off the rninbow triijcvtory along which the development of the internal degrees of freedom is calcu-Ititcd.
