A detailed study of data on pion production in proton nucleus collisions has been made in order to better understand the high value of the charged muon ratio in the range 0.2-2.0 GeV/c at the top of the atmosphere, where the muon flux is the result of the first interaction of the cosmic ray protons with the atmosphere. This paper describes a chronological study of proton nucleus, p+Be(C), collisions. An approximate factorised expression is obtained for the differential cross section for charged pion production. The multiplicity of the negatively charged pions is parameterised as function of A and ?s. A Monte Carlo simulation method is applied to calculate the charged muon ratio using the CAPRICE94 measured proton flux at float and the differential cross section distributions of the pions. Our result is compared to other simulations results and to the CAPRICE94 results.
