Steepness of the Lateral Distribution Function of Secondary Hadrons in Extensive Air Showers

Abstract

The influence of high and low energy hadronic interaction models on hadrons lateral distribution of cosmic ray air showers for primary energies 1017-1019eV is explored. By using CORSIKA simulation code hadrons lateral distribution and also steepness of the hadron lateral distribution function is studied. We have shown η (the steepness of the lateral distribution) is increases with increasing primary energy and is decreases with increasing primary mass. We have investigated hadrons lateral distribution and their dependence on the primary energy and mass of cosmic ray induced air showers. η can be directly related to the shower maximum (Xmax) and also it can suitable parameters for resolution of composition mass of cosmic ray.
