| 摘 要： | 系统地研究“颈”发射过程中的中等质量碎片,能使我们更好地理解中能核反应的动力学和热力学性质.采用具有不同的同位旋靶核研究了靶同位旋与中等质量碎片的关系,以及区分反应过程中类弹、类靶产生的中等质量碎片和“颈”发射过程中产生的中等质量碎片.HJ4/9] By systematic study of the IMF produced the “neck”emission process, one can understand much better about the dynamics and thermodymanics of the intermediate energy nuclear reaction. The isospin dependence of IMF emission was studied for the reaction system with different isospin target nucleus and the different IMF production mechanisms that originate from projectile like、 target like and the “neck” were distinguished.

| Abstract: | HJ4/9] By systematic study of the IMF produced the “neck”emission process, one can understand much better about the dynamics and thermodymanics of the intermediate energy nuclear reaction. The isospin dependence of IMF emission was studied for the reaction system with different isospin target nucleus and the different IMF production mechanisms that originate from projectile like、 target like and the “neck” were distinguished. |
