Resonances in 28Si populated in the 12C(20Ne, 28Si*)α reaction

The ¹²C + ¹⁶O decay of ²⁸Si states populated in the ¹²C(²⁰Ne, ²⁸Siast) reaction has been studied at beam energies of 160 and 110 MeV. Evidence for ²⁸Si excited states is observed for the excitation energy range of 25-45 MeV. Angular correlation analysis shows that the spins of these states lie in the range of 10-16 bar h. These measurements further indicate that these breakup states are associated with the decay of a ²⁸Si nucleus with a large deformation.
