Abstract
Calculations are presented on the fluxes of secondary particles with energies greater than 10 GeV arising from the collisions of primary cosmic rays with interstellar matter. The calculations are based on the parametrization of the accelerator data on production cross sections of pi +or-, p and deuterons in proton-proton collisions up to 1500 GeV as a function of rapidity variable for different transverse momenta of the particle produced.
