The energy spectrum of primary cosmic ray particles is determined from the analysis of the chemical composition data of high energy cosmic rays using data obtained by the Japanese American cooperative emulsion experiments for proton and helium intensities and the Goddard Space Flight Center measurements for cosmic ray nuclei. The results indicate that no pronounced changes in the abundance ratios occur at high energies. The total primary spectrum in the range 2-300 TeV is calculated and follows the form N(E)dE = 2.24 x 10 to the 4th (E to the -2.7th)dE, where E is the energy expressed in GeV nucleons and N(E) is the intensity expressed in 1/(sq m s sr GeV/nucleon). The sea level proton and neutron spectra are estimated from this primary spectrum as the source of nucleons near the top of the atmosphere using the Feynman scaling hypothesis and the conventional nucleon-atmospheric diffusion equation. It is found that the derived spectra are in accord with previously measured proton and neutron spectra.
