宇宙线高能族事例中簇射粒子的横向分布

Lateral Distribution of Shower Particles in High Energy Family Events of Cosmic Rays

对甘巴拉山铅乳胶室实验所获取的总观测能为 10 0TeV至 4 0 0TeV的高能族事例中簇射粒子的横向分布进行了分析 ,并与相应的MonteCarlo模拟计算进行了比较 .模拟计算采用的是CORSIKA程序 ,其中的强相互作用采用QGSJET模型 .结果表明 :采用CORSIKA(QGSJET)

An analysis on the characteristics of lateral distributions of the shower particles in high energy family events with visible energies 100TeV-400TeV observed in lead emulsion chambers at Mt. Kanbala (5500m a.s.l.)is done. The experimental results are compared with those of the corresponding Monte Carlo simulation. The code CORSIKA with QGSJET as the hadronic interaction model is applied in the simulation.It shows that the lateral distributions of shower particles in the simulated family events are basically in agreement with experimental data and the whole distribution tendency of the rate of energy concentration for simulation is basically consistent with experimental data.
