Abstract

Excitation functions have been measured at six angles for 24Mg(α, α)24Mg up to Eα 4.94 MeV. Multi-level R-matrix analysis was performed for nineteen resonances. More than ha of the determined spin-parities and other resonance parameters are new values. The 24Mg(α, γ)28Si studies of Maas et al. were extended up to Eα = 5.13 MeV. Resonance strengths and branchin ratios were determined. The γ-ray angular distribution measurement at Eα = 3.79 MeV gives Jπ = 2+ value for the resonance. A comparison of the results obtained in different reaction channel is given and the possibility of clusterisation in some excited states of 28Si is discussed.
