Mechanism of heavy ion fusion to superheavy nuclei

Abstract

This article reviews different models for the description of fusion of heavy ions to superheavy nuclei by using adiabatic and diabatic potentials. The dynamics of fusion is basically different in the two types of models for fusion: In the adiabatic models the nuclei melt together, whereas in the diabatic models the nuclei transfer nucleons between each other up to the instant when the compound nucleus is formed. As final result we state that diabatic potentials seem more appropriate for the description of fusion of heavy nuclei than adiabatic potentials.
