Nucleus-Nucleus (Non-monotonic) Potentials and Vector Analyzing Powers of ⁶Li Scattering by ¹⁶O

The data on the elastic scattering cross-section (CS) and vector analyzing power (VAP) of ⁶Li incident on ¹⁶O nuclei is analyzed in terms of an optical model (OM) potential, the real part of which is generated from a realistic two-nucleon interaction using the energy-density functional (EDF) formalism. The EDF-generated real part of the potential is non-monotonic (NM) in nature. This NM real potential part, without any renormalization, along with an emperically determined imaginary part and spin-orbit potential, embodying theunderlying physics of projectile excitation, can successfully account for both CS and VAP data in all cases.
