摘要: 研究了15 MeV/u 197Au+197Au 体系三裂变反应过程中体系的集体运动动能、核-核相互作用势、集体运动总动能以及核子激发能的演化过程，并讨论了该反应过程的能量耗散问题。通过与两裂变时体系总动能ε_tot 和Θ_c.m.:关联图作对比，初步得出三裂变反应体系的第一次裂变是极端深度非弹性散射过程；进一步分析了三裂变与两裂变反应体系总动能与碰撞参数的关系，发现小碰撞参数下两裂变比三裂变反应耗散的能量多大约150 MeV，大碰撞参数下三裂变比两裂变反应多消耗300 MeV。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.
