Fusion-evaporation cross sections for ⁶⁴Ni+⁶⁴Ni have been measured down to the 10 nb level. For fusion between two open-shell nuclei, this is the first observation of a maximum in the S-factor, which signals a strong sub-barrier hindrance. A comparison with the ⁵⁸Ni+⁵⁸Ni, ⁵⁸Ni+⁶⁰Ni, and ⁵⁸Ni+⁶⁴Ni systems indicates a strong dependence of the energy where the hindrance occurs on the stiffness of the interacting nuclei.
