Phenomenon of Energy Concentration in High-Energy Family Events of Cosmic Rays
Abstract： The phenomenon of energy concentration in high-energy family events of cosmic rays is studied by comparing the results of family events of total visible energies 100-400 TeV observed in Kanbala emulsion chamber experiment with the Monte Carlo simulation data. The simulation is made by program CORSIKA in which QGSJET is applied as the hadronic interaction model, and the chemical composition of primary cosmic rays is obtained from the rigidity-cut model and the extrapolation of new results of direct measurements. This shows that the whole distribution tendency of the rate of energy concentration of simulated family events is basically consistent with that of the experiment.
