Abstract

We studied the evolution of the collective motion, interaction potential, the total kinetic and excitation energies in ternary ssions of ¹⁹⁷Au +¹⁹⁷Au system at 15 Mev/u, and discussed energy dissipation of this reaction. Through the comparison with energy-angle correlation data in binary ssions, we preliminarily concluded that the rst ssion of ternary ssion was an extreme deep-inelastic process. We further analyzed the correlation of the total kinetic energy with impact parameters in both binary and ternary reactions, and found that the total energy of binary reactions systems was lost about 150 MeV more than ternary ssion with small impact parameters, and with larger impact parameters the total energy of ternary reactions were lost 300 MeV more than binary reactions.
