Description
We have studied the 28Si+24Mg system leading to the three-body final states α+24Mg+24Mg and α+20Ne+28Si. Full momentum reconstruction on an event by event basis allows us to obtain all kinematic quantities, and perform a comparison of competing reaction mechanisms. A search reveals very little evidence for the population of high-spin states in 48Cr corresponding to resonances observed in the 24Mg+24Mg system, via the 24Mg(28Si,α)48Cr/sup */(24Mg) and 24Mg(28Si,α)48Cr*(20Ne) reactions. Instead, we find that the dominant processes that occur involve inelastic heavy-ion scattering to α-particle unbound states in 28Si and 24Mg
