The elastic and inelastic scattering of the weakly bound *6Li+*9Be system at the laboratory energy of 32 MeV were studied within the optical model and coupled-channels approaches by taking into account the cluster structure of the interacting nuclei. The semi-microscopic double-folding optical potential was constructed using realistic nuclear matter densities obtained within the three-body cluster models *6Li=*a+p+n and *9Be=*a+*a+n . The calculated folding potential was first validated through the analysis of the elastic scattering angular distributions and showed good agreement with the available experimental data. The inelastic scattering corresponding to the excitation of the nucleus to the 2.43 MeV state was analyzed within the coupled-channels framework, with particular focus on the role of transition form factors. Three different transition form factors were considered and compared: the microscopic form factor calculated within the three-body *a+*a+n model of *9Be , the form factor obtained as the first derivative of the calculated double-folding potential, and the phenomenological form factor taken as the first derivative of the Woods–Saxon potential. The microscopic three-body and double-folding form factors are demonstrated to be applicable to the description of inelastic scattering, yielding results comparable to those obtained with the phenomenological approach.
