Four-alpha cluster folding model of¹⁶O-ions

Abstract

The 4 alpha -cluster structure of the 16O nucleus was proposed in order to deduce the folded optical potentials of 16O-projectiles through either the Watanabe superposition or double folding cluster models. The resultant potentials must be renormalised by factors Nr approximately=1.28+or-0.22 to fit the data. The results were compared with the standard double folding model predictions and experimental data. The alpha +16O data at 48.7 MeV are also analysed.
