摘要
对400 A MeV12C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,结果表明靶核蒸发碎片、靶核反冲质子及重电离粒子平均多重数均随靶核大小的增加而增加;靶核蒸发碎片、靶核反冲质子及重电离粒子多重数之间存在线性关联,这些结果均可以利用核-核碰撞几何模型来解释.
The multiplicity distribution and correlations of target fragments in12C induced different emulsion targets interactions at 400 A MeV are investigated.It is found that the averaged multiplicity of grey track particle,black track particle and heavily ionized track particle increases with the increase of target size.There is a linear correlation between different target fragments.The experimental results can be explained based on the geometrical picture of nucleus-nucleus interactions.
