摘要
中能区([10～100]MeV/u)是一个由平均场相互作用向核子-核子相互作用的过渡区.在这两种不同的碰撞机制之间没有明确的分界线.它们之间的并存和逐步过渡使反应机制变得相当复杂,在实验上和理论上的研究都是十分有意义的,是当前核物理的前沿领域.弹核碎裂和中等质量碎片的发射是研究反应机制变化的重要课题.对热核的形成和衰变的研究,可以拓广人们对极端条件下核物质运动规律的认识.放射性核次级束流传输线的建立将提供用放射性核进行总反应截面、弹性碰掸和其它反应过程研究的可能性.
The intermediate energy domain ([10～100]MeV/u) is a transitional region
from the mean field interaction to the nucleon-nucleon interaction.There is no clear
borderline between these two different collision mechanisms.There coexistence and progres-
sive transition make the reaction mechanism quite complicated in this energy region.The ex-
perimental and theoretical study on the reaction mechanism,which is fascinating and impor-
tant,is a frontier of nuclear physics.
Projectile fragmentation and intermediate mass fragment emission are the important sub-
jects of reaction mechanism study.The research of the formation and decay of the hot nucle-
ar system can broaden and deepen the understanding of the motion of nuclear matter under
extreme conditions.The secondary beam will provide the possibility for investigating the to-
tal reaction cross section,elastic scatting and other reaction processes by using the
radioactive projectiles.
