Fusion hindrance for Ca+Ca systems: Influence of neutron excess
The measurement of the excitation function for fusion evaporation reactions in the system 40Ca + 48Ca (Q=4.56 MeV) has been extended downward by two orders of magnitude with respect to previous cross section data. A first indication of an S-factor maximum in a system with a positive Q value has been observed. In addition a correlation between fusion hindrance and neutron excess N − Z has been found for the Ca + Ca, Ni + Ni, and Ca + Zr systems.
