摘要
对1.7 AGeV 84Kr诱发乳胶核反应慢粒子产生进行研究。实验结果表明,黑径迹粒子、灰径迹粒子和重电离粒子平均多重数随碰撞中心度及靶核大小的增加而增加;灰径迹粒子和重电离粒子平均多重数随黑径迹粒子数的增加而增加;重电离粒子平均多重数随灰径迹粒子数的增加而增加,而黑径迹粒子平均多重数随灰径迹粒子数的增加表现出先增加后趋于饱和的趋势;灰径迹粒子平均多重数随重电离粒子数的增加而增加,而黑径迹粒子平均多重数随重电离粒子数的增加表现出先增加后趋于饱和。以上结果均可利用核碰撞几何模型来解释。
The production of slow particle in 1.7 AGeV 84 ^Kr induced emulsion interaction was studied. The experimental results show that the average multiplicity of black, grey and heavily ionized track particle increases with the increase of impact centrality and target size. The average multiplicity of grey track particle and heavily ionized track particle increases with the increase of the number of black track particle. The average multiplicity of heavily ionized track particle increases with the increase of the number of grey track particle, but average multiplicity of black track particle increases with the increase of the number of grey track particle and then saturated. The average multiplicity of grey track particle increases with the increase of the number of heavily ionized track particle, but average multiplicity of black track particle increases with the increase of the number of heavily ionized track particle and then saturated. Those experimental results can be well explained by using the nuclear impact geometry model.
