The Contradiction in the EAS Muon and Hadron Data Beyond the CR Spectrum Break

摘要

The comparison of muon numbers in two groups of events:all EAS and EAS with gamma-families and hadrons,shows that problem of CR composition beyond the break becomes much more complicate then usually suggested.N_(mu)-N_e dependence shows muon abundance for EAS with gamma-families in comparison with average muon number for all EAS.The standard nuclear models predict opposite effect.The E_(gamma) spectra in EAS core become more hard at the same energy area that has be interpreted as increase of proton part in CR beyond CR break .The both effects can't be explained simultaneously by the ordinary nuclear cascades.
