Abstract:

On the basis of experimental data «Pamir» in the field of ultrahigh-energy Eest = 1016 - 1017 eV, experiment and model MS0 considered parameters α - azimuthal anisotropy of the angular distributions of the secondary particles, and depending on the space-energy characteristics ER initial gamma-families formed during the interaction of protons and alpha particles of the primary cosmic rays (PCR) with air nuclei. In the experiment, an excess Δeksp = 0.10 ± 0.02 anisotropic initial γ-families with αin > 0.2 relative to the model. Mean value in the experiment appeared in the 1.6 times higher than in the model. In the region of small values of <500 TeV·mm setting is consistent among themselves, experiment and model and make small value ~ 0.10, and in the large > 500 TeV·mm observed a sharp increase in the experimental value of the parameter with the increase in performance. The values of one discussed above models remain essentially unchanged with the increase.
