EAS Longitudinal Development and the Knee
Abstract
It is shown that EAS longitudinal development has a critical point where an equilibrium between the main hadronic component and the secondary electromagnetic one is broken. This results in a change of slope in quasi-power law function Ne(Eo). The latter leads to a knee in the EAS size spectrum at primary energy of about 100 TeV/nucleon at sea level.
