Abstract:The term fusion barrier distribution provides a clear method to test the
effect of nuclear structure on the behavior of nuclear matter and dynamics of nuclear reactions,especially for energies where penetrability effects are
considered. It presents an unexpected enhancement, as compared with convent
ional models of tunneling through a one-dimensional penetration model.The quantum mechanical barrier penetration effects play a central role, where the fusion cross section has been vanished suddenly as the bombarding energy becomes less than the barrier.We concluded that Wong form is the more exact and acceptable form to deduce the excitation functions as well as the barrier distribution for heavy ion fusion when concerning channel coupling and tunneling effects in comparison with the one dimension barrier penetration function.
