对290 AMeV ~(12)C诱发乳胶核反应末态粒子间的多重数关联进行了研究。实验结果表明:黑径迹粒子、灰径迹粒子、重电离粒子多重数之间存在较强的关联,而且黑径迹粒子和重电离粒子多重数有饱和的趋势,这些特征与高能区实验结果一致;簇射粒子与其他粒子间的关联性较弱,这一特征与高能区实验结果不同,主要归因于弹核能量较低、簇射粒子产额较小;黑径迹粒子、灰径迹粒子在前后半球的平均多重数随靶核的增大而增加;实验结果可用基于碰撞几何的旁观体-反应体模型及级联蒸发模型来解释。
The correlation of multiple numbers between the final particles of 290 AMeV ~ (12) C-induced latex nuclear reactions was studied. The experimental results show that there is a strong correlation between the black track particles, the gray track particles and the multiplicity of the heavy ionized particles, and the tendency of the number of the black track particles and the number of the heavy ionized particles to be saturated. These characteristics are in agreement with the experimental results Which is different from that of the other high-energy regions, which is mainly attributed to the lower energy of the bomb nucleus and the smaller output of the showering particles; the diameter of the black track particles, the diameter of the gray track The average multiplicity of trace particles in the anterior and posterior hemispheres increases with the increase of target nucleus. The experimental results can be explained by the paraxial body-response model based on collision geometry and the cascade evaporation model.
