Fusion cross sections have been measured for the 28Si + 12C system over the energy range 60 MeV ⪕E28Si⪕90 MeV. Large structures in the total fusion yield are identified at Ecm = 19.6, 20.6, 22.0, 23.9, and 25.1 MeV. Unlike most systems previously studied, the nucleon decay modes are largely responsible for these anomalies. The structures occur at successive integral values of angular momentum, but do not appear to correlate with known resonances in 180° elastic and inelastic scattering.
