“…The KASCADE group performed systematic studies to evaluate the influence of different hadronic interaction models used in the simulations to interpret the data on the resulting spectra for elemental groups [2][3][4][5][6]. Two sets of spectra, derived from the observation of the electromagnetic and muonic air shower components, using CORSIKA [7] with the hadronic interaction models QGSJET and SIBYLL are compiled in Fig.…”

“…Below 1 PeV the flux for protons and helium is lower than the extrapolations of the direct measurements, while at higher energies the data compare well to the poly-gonato model. [6], as well as single hadrons [8], using CORSIKA simulations with the hadronic interaction models QGSJET (left-hand side) and SIBYLL (right-hand side) to interpret the data. The energy scale of the data has been readjusted, see text.…”

“…Thus, such models ultimately arrive at a mass dependent cut-off for individual element spectra. The investigations of the KASCADE group however seem to indicate a rigidity dependent cut-off for individual elements [2][3][4][5][6]. Also with the phenomenological approach of the poly-gonato model a rigidity dependent approach is favored [1].…”

The origin of the knee in the energy spectrum of cosmic rays is an outstanding problem in astroparticle physics. Numerous mechanisms have been proposed to explain the structure in the all-particle spectrum. In the article basic ideas of several models are summarized, including diffusive acceleration of cosmic rays in shock fronts, acceleration via cannonballs, leakage from the Galaxy, interactions with background particles in the interstellar medium, as well as new high-energy interactions in the atmosphere. The calculated energy spectra and mean logarithmic masses are compiled and compared to results from direct and indirect measurements.

“…The most intriguing features of the primary cosmic ray (PCR) spectrum obtained in recent years is a rigidity dependent energy of the knee Ek(Z)=E(1)*Z (Z is the charge of a particle) and perhaps the very sharp change of a spectrum exponent at this point (by dγ ∼ 2.1) of every nuclear component of PCR [1,2], that is much more than dγ ∼ 0.5 in the 'all particle' spectrum. The confirmation of this conclusion is very important from the point of view of the cosmic ray origin problem.…”
