摘要
The KASCADE experiment measuring a larger number of EAS observables with an improved sampling of the electron-photon, hadron, and muon components than previous experiments, provides data accurate enough for an event-by-event analysis of the energy dependence of the primary cosmic ray flux in the energy range of 10(14) - 10(16) eV. Multivariate statistical analysis approaches enable to estimate the primary cosmic ray flux and the elemental composition. The major feature in the observed PeV energy region, the so called knee is reproduced, spectral indices and the knee energy are determined.
