Large deformation effects in the 28Si + 12C and 28Si + 28Si reactions

The possible occurence of highly deformed configurations is investigated in the 40Ca and 56Ni di-nuclear system as formed in the 28Si + 12C and 28Si + 28Si reactions, respectively by using the properties of emitted light charged particles. Inclusive as well as exclusive data of the heavy fragments and their associated lih+ght particles have been collected for both reactions at two bombarding energies Elab(28Si)=112 and 180 MeV by using the ICARE multidetector array. The measured energy spectra, velocity distributions, and inplane angular correlations are analysed by statistical-model calculations using a consistent set of parameters with spin-dependent level densities. The results suggest significant deformation effects at high spin for both reactions, and an unexpected cluster emission of 8Be in the 28Si + 12C reaction
