摘要

在本研究中,我们研究了 7 个 Li 核在 3A GeV/c 下与核乳剂相互作用的一般特征。研究讨论了带电二级粒子的倍率以及它们之间的相关性。研究了平均倍率、复合倍率、离散度的变化以及平均复合倍率随不同射弹和目标质量数的变化。研究结果表明,7 Li 核与乳状核之间的相互作用具有某些规律性,这些规律性以前在涉及较轻核的试验中也曾出现过。对二次带电粒子的平均倍率值进行了估算,并分析了这一平均倍率与射弹质量数的关系。撞击参数决定了二次带电粒子的平均倍率,随着撞击参数的降低,平均倍率也随之升高。讨论了喷射粒子的平均倍率随重电离粒子的变化而变化的情况。研究表明,复合倍率是研究原子核之间相互作用的一个很好的运动学参数。复合倍率的平均值大多随着射弹质量数和目标质量的增加而增加。对倍率相关性的研究表明,喷射粒子和灰色粒子具有很强的相关性。7 Li 粒子相互作用的实验数据已被有条不紊地与不同能量下的其他相互作用进行了比较;新的结果与几乎相同能量下的相应结果是一致的。目前的研究结果已经与强子-核碰撞的结果进行了比较

Some Characteristics of Relativistic Secondary Charged Particles Produced in 7Li Interaction with Nuclear Emulsion
In the present work, the general characteristics of the interactions of 7 Li nuclei with nuclear emulsion at 3A GeV/c have been studied. The multiplicity of the charged secondary particles and the correlations among them are discussed. The average multiplicity, compound multiplicity, variation of the dispersion, and the variation of the average compound multiplicity with the different projectile and target mass numbers have been investigated. The outcomes demonstrate certain regularities in the interactions between 7 Li nuclei and emulsion nuclei, which were previously seen in tests involving lighter nuclei. The values of the average multiplicity of the secondary charged particles have been estimated, and the dependence of this average multiplicity on the mass number of the projectile has been analyzed. The impact parameter determines the average multiplicities of the secondary charged particles, which rise as the impact parameter decreases. The variation in average multiplicities of shower particles as a function of heavy ionizing particles has been discussed. The compound multiplicity has been shown to be a good kinematical parameter for studying the interaction between nuclei. The compound multiplicity's average value mostly rises as the projectile mass number does and with the target mass. The study of multiplicity correlations has shown that shower and grey particles are strongly correlated. The 7 Li interaction's experimental data have been methodically compared to other interactions at various energies; the new results are consistent with the corresponding results at almost the same energy. The results obtained in the current studies have been compared with those from hadron-nucleus collisions
