EAS data at the mountain level and a shape of the CR spectrum beyond the break

In the most works which deal with EAS the CR energy spectrum is deduced by means of the model defined dependence $E_0=a\cdot {N_e}^{\alpha }$. An electron total number $N_e$ is evaluated by integration of the NKG-function f®. This algorithm breaks down for young EAS with age parameter $s\sim 0$. This work shows, that part of the young EAS becomes large in the range $N_e\ge {10}^7$, it cause to divergency of the $N_e$ integral for them and distorts the shape of EAS (CR) spectrum. A final analysis of the experimental data permits to conclude that EAS spectrum has local maximum at $N_e\sim {10}^9$, which results in a decrease of the EAS spectrum slope for $N_e\ge {10}^7$ (inverse break or “knee”). A local maximum can arise because of the additional CR component in the range $E_0\ge 10$ PeV.
