Abstract
The one-dimensional barrier penetration model was successfully applied in description of excitation function for complete fusion of 58Ni + 58Ni system, particularly at far sub-barrier energies. Using different nuclear potentials (KNS, proximity, empirical SWW and NGÔ) a strong sensitivity to changes in nuclear radius parameter r0 (∆ r0 < 0.065) was established for fitting this high precision data. The minor monotonic increase of r0 with decreasing energy was manifested in geometry of the barrier and the attractive nature of the nuclear potentials (involved) in the surface region.
