Abstract
The directly measured elemental spectra of primary cosmic rays obtained from JACEE, MSU, SOKOL and CRN data on p, He, CNO, Ne-S and Fe fluxes have been considered for the calculation of elemental nucleon spectra at the top of the atmosphere. Treating these spectra as parents of the secondary mesons, the sea-level muon fluxes at zenith angles 0 7 and 897 from each species have been derived using Z-factors based on the FNAL cross-section data for meson production and duly corrected for A-A collisions. The conventional muon spectra at 07 and 897 estimated from the individual elemental spectra and the prompt muon contribution arising from the charmed meson decays have been found comparable with the directly measured muon fluxes determined by Thompson et al., Allkofer et al., Matsuno et al., Khalchukov et al., Ivanova et al., Afanesieva et al., Bakatanov et al., Gettert et al. and Zatsepin et al. The muon spectra derived from the primary nucleon spectrum with a constant spectral index of value 22.73 are found in approximate agreement with the present results.
