TLDR
In this paper, three values of the differential exponent, namely 2.65, 2.70 and 2.75, of the primary cosmic-ray nucleon spectrum, the scaling model of high energy N-N collisions parametrised from the recent ISR data and a realistic model for the propagation of cosmic rays through the atmosphere, the sea-level vertical muon spectra in the energy range 0.5-103 GeV have been derived.Abstract:
Using three values of the differential exponent, namely 2.65, 2.70 and 2.75, of the primary cosmic-ray nucleon spectrum, the scaling model of high-energy N-N collisions parametrised from the recent ISR data and a realistic model for the propagation of cosmic rays through the atmosphere, the sea-level vertical muon spectra in the energy range 0.5-103 GeV have been derived. By comparing the results with the recent muon data of Allkofer et al. (1971) it can be concluded that the primary cosmic-ray nucleon spectrum may be represented by a single exponent over the whole energy range 5-104 GeV, and is given by the relation D(EN)dEN=2.48EN-2.70dEN. This conclusion is not in agreement with the results of some recent similar calculations.read more

On the interpretation of the primary cosmic-ray energy spectrum of Grigorov et al
TL;DR: The integral energy spectrum of all primary cosmic-ray particles in the energy range 50-106 GeV presented by Grigorov et al. (1970, 1971) in a series of proton satellite experiments has been used to derive the differential energy spectrum with the help of the recent knowledge of the mass composition of primary cosmic rays as discussed by the authors.
