<p>This study investigates the mechanism of ⁶Li+⁷Li anomalous large-angle scattering. First, elastic scattering is analyzed using an optical model with the São Paulo potential, and inelastic scattering to the first excited state of ⁷Li is analyzed by distorted wave born approximation method. The experimental data of the elastic scattering angular distributions could be described reasonably well by the optical model at forward angles; however, anomalous large-angle scattering is observed in the angular distributions of both the elastic and inelastic channels for all measured energies. Elastic and inelastic scatterings are investigated using the coupled reaction channel method. The elastic and inelastic scattering, transfer reactions for the ground and excited states, and their coupling effects are considered in the coupled reaction channel scheme. In addition, the influence of the breakup effects of the weakly bound ⁶Li and ⁷Li is investigated by including three resonance states of ⁶Li and two resonance states of ⁷Li in the coupled reaction channel framework. The observed anomalous large-angle scattering is explained using the transfer reaction mechanism and breakup effect, and the calculated results reproduce the experimental data reasonably well.</p>
