Abstract

A total of 107 cascades formed by secondary particles of the nuclear interaction of an astroparticle with an energy of ∼1016 eV are detected in a stratospheric emulsion chamber. Their azimuthal distribution revealed a distinct anisotropy. The elliptic flow coefficient V 2 was estimated at 0.35 ± 0.02. The average transverse momentum of cascades in the direction of the impact parameter exceeded 3 GeV/c.
