All particle primary nucleon spectrum derived from the latest jacee data

The all-particle primary nucleon spectrum has been estimated on the basis of the latest JACEE data on the fluxes of p, He, C, N, O, Ne, Mg, Si, and Fe. Up to the observed energy level of 10 to the 14th eV, no change was seen in the primary spectral index or in the primary chemical composition, and n...

Description
Summary:The all-particle primary nucleon spectrum has been estimated on the basis of the latest JACEE data on the fluxes of p, He, C, N, O, Ne, Mg, Si, and Fe. Up to the observed energy level of 10 to the 14th eV, no change was seen in the primary spectral index or in the primary chemical composition, and no heavy nuclei dominance phenomena were observed. The low energy fit extrapolated results follow a power law fit of a given form. The concept of nuclear fragmentation was used to estimate the nucleon flux from nuclear spectra, and the results agree with the theoretical prediction of Yodh et al. (1981). (C.D.)
