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 pp
®p± 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 Zpp = 0.499,sgN = 0.119 mb
and spA = 198 mb. It exhibits a drastic decrease
with energy.
