The experimental fusion excitation functions of the reactions Ti48+Fe58 and Ni58+Fe54, measured down to the low sub-barrier energies, are described within the quantum diffusion approach and the universal fusion function representation. For these systems, the s-wave capture probabilities are extracted from the experimental excitation functions and are also analyzed. An enhancement of the sub-barrier fusion cross section observed in the Ti48+Fe58 reaction in comparison to the relatively close system Ni58+Fe54 is explained.
