Sub‐barrier Fusion Cross Sections with Energy Density Formalism
We discuss the applicability of the energy density formalism (EDF) for heavy‐ion fusion reactions at sub‐barrier energies. For this purpose, we calculate the fusion excitation function and the fusion barrier distribution for the reactions of 16O with 154,144Sm, 186W and 208Pb with the coupled‐channels method. We also discuss the effect of saturation property on the fusion cross section for the reaction between two 64Ni nuclei, in connection to the so called steep fall‐off phenomenon of fusion cross sections at deep sub‐barrier energies.
