Decay modes of highly excited nuclei

The deexcitation of single excited 112 Sn nuclei at T = 1–30 MeV is simulated using the isospin-dependent quantum molecular dynamics (IQMD) model and GEMINI model. The fragmentation mechanism, critical behavior, and kinematic characteristics are investigated within these two models. The results show that the IQMD model can be applied to the analysis of fragmentation processes, critical points, and slope temperature extraction. The results of IQMD are generally consistent with experimental ⟨ M IMF ⟩ - Z bound data. However, GEMINI can reproduce the experimental data better than IQMD for isotopic distributions.
