The possible occurence of highly deformed configurations is investigated in the 40Ca and 56Ni di-nuclear systems 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 (A ≥ 6) and their associated light charged particles (p, d, t, and α-particles) have been collected at the IReS Strasbourg VIVITRON Tandem facility with two bombarding energies Elab(28Si) = 112 and 180 MeV by using the ICARE charged particle multidetector array, which consists of nearly 40 telescopes. The measured energy spectra, velocity distributions, in-plane and out-of-plane angular correlations are analysed by Monte Carlo CASCADE statistical-model calculations using a consistent set of parameters with spin-dependent level densities. Although significant deformation effects at high spin are needed, the remaining disagreement observed in the 28Si + 12C reaction for the S evaporation residue suggests an unexpected large unstable 8Be cluster emission of a binary nature.
