Abstract

We present an upper limit of galactic diffuse gamma-ray flux, measured withthe GAMMA experiment at energy about 175 TeV. The results were obtained usingselection of muon poor extensive air showers at mountain level (700 g/cm^2, Mt.Aragats, Armenia) for 5 GeV muon energy threshold. An upper limit for thedifferential flux at energy E=175+/-25 TeV is equal to (5.8-7.0)x10^-12 [ergm^2 s sr]^-1 for 95% confidence level.
