高能强子与原子核碰撞的受伤核子数分布和非弹性截面的计算

Calculation of Cross-Section and Distribution of Number of Wounded Nucleons in High Energy Hadron-Nucleus Inelastic Collision

在对超高能区宇宙线产生的广延大气簇射的模拟计算中注意到，质子—空气核碰撞中的受伤核子数分布和非弹性截面对于簇射的纵向发展有着重要的影响．本文依据符合现有加速器能区的有关质子—质子作用截面的经验公式，对超高能区的质子与空气核碰撞的受伤核子数分布和非弹性截面做了计算．

The inelastic cross-section and the distribution of the number of wounded nucleons in proton-Air collision have significant influence on the development of EAS caused by superhigh energy cosmic rays.Based on the data of pp crosssection from accelerator experiments,the inelastic cross-section and the distribution of the number of wounded nucleons in proton-Air collision have been calculated at superhigh energy region.
