Abstract

A high-quality measurement of proton and α-particle emission associated with fusion of Si28,30,32 with a Si28 target is described. Evaporation residues produced by de-excitation of the compound nucleus were identified by an energy time-of-flight measurement while emitted light-charged particles were identified using the ΔE-E technique. Comparison of the experimentally measured charged particle multiplicities and energy spectra with the predictions of the statistical decay model code GEMINI++ allows one to deduce interesting details of the de-excitation cascade and its dependence on neutron-excess. The impact of modifying the sequence of particle emissions on the average energy and multiplicity is examined.
