Using the skyrme energy density formalism, a pocket formula is introduced for barrier heights and positions of 95 fusion reactions(48≤ZPZT≤1520) with respect to the charge and mass numbers of the interacting nuclei....Using the skyrme energy density formalism, a pocket formula is introduced for barrier heights and positions of 95 fusion reactions(48≤ZPZT≤1520) with respect to the charge and mass numbers of the interacting nuclei. It is shown that the parameterized values of RBand VBare able to reproduce the corresponding experimental data with good accuracy. Moreover, the absolute errors of our formulas are less than those obtained using the analytical parametrization forms of the fusion barrier based on the proximity versions. The ability of the parameterized forms of the barrier heights and its positions to reproduce the experimental data of the fusion cross section have been analyzed using the Wong model.展开更多
