On some peculiarities of extensive air showers initiated by gamma-rays of extremely high energies

Abstract

The number of low-energy muons (E{sub {mu}} {<=} 1 GeV) in extensive air showers (EAS) initiated by primary gamma-rays of extremely high energies is calculated. It is shown that at large depths (z {>=} 1000 g/cm{sup 2}) the number of low-energy muons in EAS from gamma-rays with energy E{sub 0} {>=} 10{sup 18} eV is of the same order as in the proton-induced shower, as opposed to the energy range E{sub 0} {approx} 10{sup 15} eV, where the gamma-showers are muon-poor. The influence of the Landau-Pomeranchuk-Migdal effect and of the interaction of the primary photon with the geomagnetic field on the development of an electromagnetic shower in the Earth atmosphere at energies E{sub 0} {>=} 10{sup 19} eV is investigated. 22 refs.; 6 figs.
