We construct a simple optical potential for nucleus-nucleus processes by a folding method. With these potentials, we have obtained high-quality fits to a variety of elastic-scattering data. We also successfully reproduce one-particle transfer data. However, two-particle transfer results may indicate the need for further refinements of the model. In addition, we calculate the bound states of an $\alpha$+${}_{}{}^{16}{}_{}{}^{}\mathrm{O}$ folded potential. There is good agreement with experimental energies and $\alpha$ widths for two $\alpha$-cluster bands in ${}_{}{}^{20}{}_{}{}^{}\mathrm{Ne}$.
