【 摘 要 】

The fusion barrier distribution (Dfus) for the systems 16O+144Sm and 16O+208Pb systems had been analyzed in this work to test the benefit of using second derivative of Wong's formula for fusion cross section to extract Dfus from experimental data. The calculated Dfususing Wong's formula compared with the result of three-point difference formula, which is the usual method for extract Dfus from experimental cross section. The results showed that this method generated the fusion barrier distribution for both systems in an acceptable approach with respect to the relative position of distribution peaks when it is compared with the theoretical calculations and three-point difference formula.
