Popis: A folding potential describing the $\alpha$ -scattering on 16O over a broad energy range 25.8-146.0 MeV is constructed on the basis of $\alpha$ -like cluster and unclustered-nucleon configurations of 16O. The resulting potential does not need any renormalization to fit the angular distribution of elastic cross-sections. The effects of the repulsive part of $\alpha$ - $\alpha$ and $\alpha$ -nucleon interactions are investigated. The analysis suggests that both the $\alpha$ - $\alpha$ repulsive potential and the unclustered nucleonic configuration in the target are important to describe the scattering data over a broad range of incident energies. The root-mean-square radius for the 16O nucleus is deduced.
