Abstract
The derivation of integral energy spectrum of muons produced by the interactions in gamma-ray showers induced by energetic photons from the Geminga pulsar has been made. The conventional analytical procedure of Drees et al. has been adopted for muon-number calculations from photoproduced air showers. The FNAL data on πp → π± X inclusive reactions, and the HERA ep collider results have been used for the evaluation of the hadronic energy moments and the photonuclear cross-sections, respectively. The integral number of muons was derived for Zππ = 0.499,σγN = 0.119 mb and σπA = 198 mb. It exhibits a drastic decrease with energy.
