摘要: 本文对中能重离子碰撞中热核的形成过程和稳定性作了评述,特别讨论了动力学效应和中间质量碎片的平衡和非平衡特征. The formation process and stability of hot nucleus produced in heavy ion collision(HIC)at intermediate energy range have been reviewed.The dynamical effect and equilibrium and non-equilibrium charactristies of intermediate mass fragments(IMF) are especially discussed.
