Isotopic effects in sub-barrier fusion of Si + Si systems

NUCLEAR REACTIONS ³⁰Si(³⁰Si, X), E=47-90 MeV; measured fusion evaporation residues (ERs), fusion σ(E) at the XTU tandem accelerator facility of LNL-INFN-Legnaro. Comparison with previous experimental results, ²⁸Si+²⁸Si data, and with theoretical calculations using coupled-channels method with aM3Y+repulsion potential, and including one- and two-phonon excitations and the mutual excitations of the low-lying 2+ and 3- states in projectiles and targets.
