From binary fission to multifragmentation in the decay of heavy excited nuclei
The decay modes of heavy excited nuclei formed in dissipative collisions for the systems Ar + Au at 60 MeV/u and Kr + Au at 43 MeV/u are studied. A transition from binary fission towards multi-fragment emission is observed around 3 MeV/u excitation energy, independently of the considered system. The...

| description | The decay modes of heavy excited nuclei formed in dissipative collisions for the systems Ar + Au at 60 MeV/u and Kr + Au at 43 MeV/u are studied. A transition from binary fission towards multi-fragment emission is observed around 3 MeV/u excitation energy, independently of the considered system. The charge distributions of the three target-emitted fragments suggest a smooth change from “fission” events (as a “natural” continuity of binary fission) to “residue production” then to “symmetric ternary fragmentation” events when the excitation energy increases from 3 MeV/u to 5 MeV/u. |
