This investigation analyzes the angular distributions (ADs) for the 7Li + 138Ba elastic scattering system across laboratory energies of 21–32 MeV using multiple nuclear potential approaches. Several computational methods were applied to assess the relative impacts of 7Li breakup and neutron transfer processes, particularly examining how the 138Ba(7Li,6Li)139Ba stripping reaction affects the elastic scattering channel. Our calculations demonstrate that 7Li breakup dominates over neutron transfer contributions in this system. Volume integrals for the real and imaginary potentials near the Coulomb barrier yield evidence for the existence of a breakup threshold anomaly.
