Description
With the data of recent measurements of the JACEE, RUNJOB and SOKOL experiments, and under the assumption of rigidity cut-off model, a new primary cosmic-ray energy spectrum and chemical composition in 1014-1016 eV energy region are derived. EAS simulations using CORSIKA, combining QGSJET model of high energy hadronic interaction, are performed with this spectrum and another two spectra, HD and PD spectrum, respectively. It is shown that the new spectrum and HD can give very good results, compared with the experimental results obtained with thick Pb emulsion chambers (28 c.u.) at Mt. Kanbala (5500 m a.s.1., Tibet, China), while PD spectrum can not
