[en] Fusion-evaporation cross sections of ³⁶S+¹⁴⁰Ce have been measured around the Coulomb barrier. A rather inert nucleus (³⁶S) has been chosen as projectile; the main effect of its rather high-energy 3- and 2+ states is to renormalize the potential. The target (¹⁴⁰Ce), has a magic neutron number (N=82), and is characterized by a strong octupole coupling strength. This combination of properties resembles the system ¹⁶O + ¹⁴⁴Sm the main difference being the larger nuclear charge of ³⁶S compared to ¹⁶O leading to stronger channel couplings. The target was chosen in order to minimize fission probability in our energy range. Transfer reactions should also be of little importance due to the negative Q-values. So ³⁶S + ¹⁴⁰Ce seems to be ideally suited to shed light on the effect of inelastic couplings on sub-barrier fusion
