Abstract
In this paper, the angular distributions (ADs) for Li-6 + Al-27 and He-6 + Al-27 elastic scattering in the energy range of 7-88 MeV and 9.5-13.4 MeV, respectively, are reanalyzed utilizing various phenomenological and microscopic potentials. The purpose of this work is to investigate the cluster nature of the weakly stable Li-6 and the two-neutron halo He-6 projectiles to check the associated breakup effects on the scattering data and to examine the consistency of the results obtained across different implemented potentials. A novel semi-microscopic dynamical polarization potential is applied to the Li-6 + Al-27 system to simulate the coupling effects on the breakup channel. The ADs for the He-6 + Al-27 system are described using the continuum discretized coupled channels (CDCC) method, which considers the coupling to the resonant (2(+), 1.8 MeV) state and twelve continuum bins belonging to L = 0, 1, and 2 states as per the adopted model for truncation and discretization of the continuum.
