Abstract.

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.
