研究了15 Me V/u197Au+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εtot和Θc.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 Me V,大碰撞参数下三裂变比两裂变反应多消耗300 Me V。
The kinetic energy of collective movement, the nuclear-nuclear interaction potential, the collective kinetic kinetic energy and the excitation energy of nucleus during the triple fission reaction of 15 Me V / u197Au + 197Au system were studied. The energy dissipation problem. By comparing the total kinetic energy εtot and Θc.m. of the two fission systems, we can conclude that the first fission of the three-fission reaction system is an extremely deep inelastic scattering process. Furthermore, the relationship between the three fission and two fission reaction systems It is found that the energy of two fissions is about 150 MeV more than that of the triplet fission reaction under the small collision parameters and 300 MeV over the two fission reactions under the large collision parameters.
