Description
We investigate the applicability Wong formula for heavy-ion fusion cross sections. Though this well-known formula gives almost exact results for single-channel calculations of relatively heavy systems, it overestimates the cross section for light systems. Thus, it is interesting to know how heavy a system should be in order for the Wong formula to work We perform a systematic calculation of heavy-ion reactions from light to heavy nuclei and determine the deviation between exact and Wong approximation. The results show that the deviation decreases as the mass of the target nuclei increases and becomes saturate at around Z ~ 20 and A ~ 50 (Z, A= atomic and mass number of target nuclei). Furthermore, the deviations decrease more rapidly for heavier projectiles than that of lighter ones.
