Comparison of non-monotonic and monotonic potentials for cross-sections and analyzing powers of 6Li elastic scattering on 12C at 30 MeV

Abstract

The experimental angular distributions of differential cross-section (CS), vector analyzing power (iT₁₁) and tensor analyzing powers (T₂₀, T₂₁ and T₂₂ ) for the ¹²C(⁶Li, ⁶Li)¹²C elastic scattering at laboratory energy of 30 MeV are simultaneously analyzed in the structure of simple optical model (OM) using shallow Non-Monotonic (NM) and deep Monotonic Woods-Saxon (MWS) potentials. The Pauli-laden energy density functional (EDF) theory which results in NM potentials is also discussed. Equally good fits to the CS, T₂₀, T₂₁, and T₂₂  data are obtained using both NM and MWS potentials. But  iT₁₁data is only reproduced well using NM potentials in OM. The conclusion is that the shallow NM potentials seem better than the deep MWS for simultaneous description of the CS, iT₁₁, T₂₀, T₂₁ and T₂₂ data.
