Bose-type distribution and primary cosmic ray nucleon spectrum from sea-level muon spectrum

Abstract

The recent CERN Intersecting Storage Ring cross section data on the p+p to pi +or-+X inclusive reactions have been analysed using the Bose-type distribution of the form E(d3 sigma )/(d3p)=(Axs12/)/(exp( epsilon ( lambda )/T)-1) proposed by Hoang (1973). This formula has been used to derive the cosmic ray primary nucleon spectrum from the sea-level muon spectrum. It is found that the primary spectrum obeys the following relation: N(Ep)dEp=2.06Ep-2.64dEp. The result has been compared with the recent experimental data and theoretical predictions given by different authors.
