摘要
Near- and sub-barrier fusion cross sections have been measured for the system Ni-58 + Fe-54, and the fusion barrier distribution has been extracted. The measured cross sections cover the range from similar or equal to 1 mu b up to around 500 mb. Close analogies are found between the extracted barrier distribution and the available data on Ni-58 + Ni-60, indicating the dominating influence of complex surface vibrations on the fusion of Ni-58 + Fe-54. The present data on Ni-58 + Fe-54 are well reproduced by standard coupled-channels calculations in the measured energy range, including quadrupole and octupole phonons in both colliding nuclei.
