中能区类弹碎片中质比的靶核相关性

Target-Dependence of Neutron-Proton Ratio of the PLF Produced in Heavy Ion Collisions at Intermediate Energies

基于实验测量并结合模型分析，讨论了中能区重离子周边碰撞过程中出射的类弹碎片（PLF）的中质比（N／Z）与靶核N／Z相关现象的产生原因．

In this paper, the target-dependence of neutron-proton ratio of the projectile-like fragments, prepuced in the peripheral heavy-ion collisions, is discussed based on the comparison between the experimental results and the isospin dependent QMD model calculahons.
