- Abstract
We have studied the emission of light unbound clusters,8Be and12C *(0+2), in the reactions18O +13C ?{31} Si ?{23} Ne +8Be and28Si +24Mg ?{52} Fe ?{40} Ca +12C *(0+2). The ?-ray spectra obtained in coincidence with8Be and12C *(0+2) emission have been studied relative to the statistical emission of two or three a-particles. The angular-momentum-to-energy balance of the cluster emission is compared with that of multiple-a emission. The properties of the energy spectra of the binary process and the population of the residual nuclei by cluster emission are discussed. It is observed that cluster emission carries away less excitation energy on average than the sequential emission of the individual components.
