Neutron-Excess Dependence of Particle Emission Order in Fusion-Evaporation
How an excited compound nucleus formed by heavy-ion fusion sheds energy by emitting protons, neutrons and alpha-particles in a de-excitation cascade, and how the ordering of those emissions shapes the measured particle multiplicities and energy spectra. Using 28,30,32Si + 28Si reactions and comparison to the GEMINI++ statistical decay code, it shows the emission order and its observables depend on the neutron excess of the fused system, probing whether alpha-cluster structure survives fusion into neutron-rich nuclear matter.
