An anti-knee

By Igor Lebedev


The energy spectra for five elemental groups (p, He, C, Si, Fe) of cosmic rays, are simulated. Calculations are based on an analysis of superposition of few cosmic ray sources (Supernovae of different types) and principles of diffusive shock acceleration. Results of the analysis in the knee region show that summarizing energy spectra for elemental mass groups of cosmic rays can have significant oscillations of spectral index $\gamma$. Moreover, a kink (increasing $\gamma$) in Fe spectrum at energy $2\cdot 10^{15}$ eV, is discovered. In order to distinguish from the knee (decreasing $\gamma$) the kink can be called an anti-knee (increasing $\gamma$).Comment: 6 pages, 4 figure
