Comparison between the zero point motion and generalized frozen approximation models in accounting for heavy-ion fusion data

Abstract

In recent papers, we have proposed two different models to calculate fusion cross sections for heavy-ion systems, based on coupled-channels calculations involving harmonic vibrations of the nuclear densities. The parameter-free S\~ao Paulo potential is assumed as the bare interaction and, therefore, the calculations are performed without any adjustable parameter. In the present work, we compare the results of these models in accounting for fusion data of approximately 60 different systems.
