Abstract: (APS)
The Kiel experiment found that the average density of muons in gamma showers from Cygnus X-3 is 80% of that of nucleon-induced air showers. We therefore calculated again the muon content of photon-induced showers. Our calculations confirm the widely held belief that gamma showers should be μ-poor and that this should indeed be a discriminating signature for electromagnetic origin of a shower.
