Extensive investigation of the 6Li + 27Al and 6He + 27Al systems using different models

Abstract

Abstract In this paper, the angular distributions (ADs) for 6Li + 27Al and 6He + 27Al 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 6Li and the two-neutron halo 6He 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 6Li + 27Al system to simulate the coupling effects on the breakup channel. The ADs for the 6He + 27Al 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.
