Abstract content
The large area tracking muon telescope in the GRAPES-3 experiment allows determination of the muon content of the detected extensive air showers with good precision. Detailed Monte Carlo simulations have been carried out to determine the muon content of nucleon induced showers. Using the results of these simulation we try to identify the sample of potential gamma induced showers in the data. From an analysis of GRAPES-3 data, we put an upper limit on the ratio of proton to gamma at 50 TeV and above. The results of this analysis would be presented.
