Abstract

We present a spectrum of primary galactic particles with energies of 10 TeV < E0 < 500 TeV, obtained from the data of reprocessing of events related to nucleon‒nucleus interactions measured in four X-ray emulsion chambers (RECs) exposed in the stratosphere at ∼10 g/cm2 for 6‒7 days in the Russian‒Japanese RUNJOB balloon experiment. The spectrum agrees within statistical errors with the proton spectrum published on the results of the final processing of the RUNJOB experiment [1]. The presented spectrum of galactic particles includes events with found and missing single-charged primary particles in nucleon‒nucleus interactions, and is compared with the spectrum constructed only from events with detected primary protons and the final spectrum of the cosmic ray proton component of the RUNJOB experiment.
