| 摘 要： | 对150 AMeV 4He,290 AMeV 12C,400 AMeV 12C,400 AMeV 20Ne及500 AMeV 56Fe诱发乳胶不同靶核反应靶核碎片多重数分布及关联进行了研究。结果表明,黑径迹粒子、灰径迹粒子及重电离粒子平均多重数随靶核大小的增加而增加,不同靶核碎片多重数之间存在线性关联。这些实验结果均可以依据核-核碰撞几何模型及级联蒸发模型来解释。

| Abstract: | The multiplicity distributions and correlations of target fragments produced in 150 AMeV 150 AMeV 4He，290 AMeV 12C，400 AMeV 12C，400 AMeV 20Ne and 500 AMeV 56Fe induced different emulsion target interactions are investigated. It is found that the averaged multiplicity of grey track particle,black track particle and heavily ionized track particle increase with the increase of target size.There is a linear correlation between the multiplicity of different target fragments. The experimental results can be well explained based on the geometrical picture and the cascade evaporation model of nucleus-nucleus interactions. |
