Abstract
A total of 43 resonances was observed by bombarding Si-28 With 14.3 - 15.4 MeV alpha particles. Of these 26 were observed in both the elastic and inel astic channels. A dominant angular momentum of L = 8 was assigned to most o f the resonances based on the analysis of differential cross-sections measu red in five keV steps at nine backward angles between 150 and 173 degrees. Auto-correlation of the elastic excitation function yields a mean resonance width of 20 keV.
