A single-folding (SF) model analysis has been performed for {alpha} and deuteron elastic scattering from {sup 58}Ni, {sup 90}Zr, {sup 116}Sn, and {sup 208}Pb at incident energies between 10 and 100 MeV/nucleon with the Lane-consistent Bruyeres Jeukenne-Lejeune-Mahaux model nucleon-nucleus potential. The energy dependence of a set of only three potential parameters was derived, and the resulting global optical model potentials were found to account well for {alpha} and deuteron elastic scattering within their studied energy ranges. The energy dependence of a real potential form factor is found to be important for describing {alpha}-nucleus scattering within large energy ranges. Corrections due to the compositeness of projectiles to the SF potentials were studied and were compared with theoretical estimations through the renormalization factor. Systematic differences in renormalization factors between {alpha} particles and deuterons were observed.
